The Fiancé He Severely Underestimated

My fiancé Jax and I built our Las Vegas empire from nothing. After fifteen years, he betrayed me for a "pure" girl named Ember, sacrificing a piece of our empire for her. He told our friends I was "too ruthless," and that he only felt "human" with her.

He arrogantly believed I could never leave, that I needed our empire-and him-too much.

To prove her victory, Ember found my mother's last keepsake, a small music box, and shattered it at my feet.

The man I'd sacrificed everything for saw me as a cold, calculating machine. He thought I was ruthless? He hadn't seen anything yet.

He believed I couldn't leave him. He was about to lose everything.

I picked up the phone and made a single call to his estranged, powerful family in D.C.

"Send him home," I said, my voice ice. "He's all yours."

Chapter 1

The diamond on my finger felt like a lie, a sparkling testament to a betrayal I hadn't yet uncovered. It was the ring Jax had slipped on my hand just last week, at the Bellagio fountains, a public spectacle that had sealed our legend as Las Vegas' s King and Queen. Everyone believed our fifteen-year partnership, built from nothing, was about to become official. I believed it too.

We were a testament to defiance, Jax and I. From the grimy back alleys to the gleaming penthouse suites, we had clawed our way up, side by side. Every scar, every victory, we shared. Our empire wasn't just built on concrete and ambition; it was forged in a fire that only two people who had nothing could understand. We were an unstoppable force, a legend in the making. That proposal, under the dancing waters, felt like the culmination of everything. It felt like forever.

My phone vibrated, slicing through the manufactured calm of my office. It was Carlisle, my head of security, his voice tight.

"Ava," he said, no preamble. "It's Jax. And Harris. Again."

A cold knot formed in my stomach. Gonzalo Harris. Our rival, the old-guard casino owner we' d been trying to squeeze out for months. Jax and Harris clashing wasn't new. It was business. But Carlisle's tone hinted at something more.

"What happened?," I asked, my voice flat, betraying nothing. My heart, however, was already starting to thunder against my ribs.

"It's... different this time," Carlisle hedged. "He's at the old warehouse we used for the downtown acquisitions. Harris is in bad shape. And there's a girl."

A girl. The words hung in the air, a silent accusation. My blood ran cold, a wave of nausea washing over me so violently I had to grip the edge of my desk. A girl. Not business. Not a negotiation gone wrong. This was something else entirely. My years of ruthlessness, my hardened exterior, felt like a thin veneer momentarily.

I took a deep, shuddering breath, forcing the weakness down. "Send me the location," I commanded, my voice regaining its steel. "And arrange for a clean-up crew. No loose ends." I had to see it for myself. I had to know. The doubt was a poison, and I needed an antidote, no matter how bitter.

The warehouse was a scene ripped from a nightmare. The air hung thick with the metallic tang of blood and the acrid smell of burnt wiring. Gonzalo Harris lay on the concrete floor, a crumpled heap, his face a mask of purple and red. My gaze, however, was drawn past him, to Jax.

He was standing over a young woman, his body a shield, his eyes fixed on her as if she were the only thing in the world that mattered. Ember Craig. The name, whispered to me by Carlisle on the drive over, felt foreign, wrong. Her clothes were artfully torn, her face streaked with dust and tears, but she looked... fragile. Innocent. Jax' s hand was on her arm, his thumb stroking her skin with a tenderness I hadn't seen directed at me in years. It was a raw, visceral infatuation that hit me harder than any punch.

"Well, well, if it isn't the Queen of Hearts," Harris rasped, pushing himself up on one elbow, his voice thick with malicious glee despite his injuries. "Come to see your king play hero for his little muse?" He spit, a bloody gob landing near my polished heels. "Jax here just sacrificed a multi-million-dollar deal, a piece of your precious empire, for this little street urchin."

Jax whirled, his eyes blazing, a predatory glint flashing in their depths. He didn't even look at Harris. His gaze was locked on me, a mixture of guilt and defiance. But it was quickly replaced by a furious protectiveness as he stepped fully in front of Ember.

"Shut your mouth, Harris," Jax snarled, pulling a gun from his waistband. The click of the safety being disengaged echoed in the cavernous space.

I watched, numb, as Jax aimed the gun, not at Harris's head, but at his kneecap. The shot cracked, loud and brutal. Harris screamed, a primal sound of agony, clutching his shattered limb. Jax didn't flinch. His eyes, dark and unseeing, never left Ember.

My stomach churned, but no new emotion registered. Just a cold hollowness. This wasn't the Jax I knew. Or maybe, this was exactly who he always was, just uncovered.

"Now, now, Jax," Harris groaned, blood seeping through his fingers. "Let's not be hasty. You care so much for this little bird, don't you? What if I told you I have her family? Her little brother, perhaps? A simple trade. You walk away from our properties, leave Vegas to me, and your precious Ember and her family walk free."

Jax froze, his face paling. He looked from Ember, who was now trembling visibly, to Harris, then back to Ember. The conflict was clear. His empire, our empire, or this girl. I knew the answer before he did.

A memory flashed, sharp and painful. Ten years ago, a nascent deal, a crooked city councilman threatening to expose sensitive information about our struggling business. Jax had been ready to concede everything. I had intervened, ruthless and cold, silencing the man, saving our future. He had called me his savior then, his rock. Now, he was ready to burn it all down for a girl.

"Don't you dare," I said, my voice cutting through the tension, flat and emotionless. I stepped forward, past Jax, ignoring his bewildered look. I pulled out my own phone. "Carlisle, execute the contingency plan for the Harris acquisition. All properties. Every last one. And send a medic for Harris. He's no longer a threat."

I looked at Jax, my eyes like chips of ice. "And you," I said, my voice barely above a whisper, "take your little project and go. Get out of my sight."

Jax stared at me, then at Ember, then back at me. He hesitated for a fraction of a second, a silent plea in his eyes, but it was too late. He gently took Ember's hand, his fingers intertwining with hers, and led her out of the warehouse. He didn't look back.

I watched them go, two silhouettes against the harsh glare of the streetlights. My feet moved on their own, following the echoes of their retreating footsteps. I needed to know where they were going. I needed to see just how deep this cut was. They led me to the dilapidated apartment building on the outskirts of downtown, the one with the fire escape and the peeling paint. Our first apartment together. The place where we had dreamed, where we had promised each other forever.

My heart didn't break. It splintered. Carlisle's voice intruded, a quiet murmur in my ear through the hidden earpiece. "His affair with Ember. It's been going on for months, Ava. Since the Bellagio proposal, even earlier." The words were an axe, chopping through any lingering hope. Months. The proposal was a lie. The whole legend, a sham.

I stood there, listening to the muffled sounds of their intimacy from inside our old apartment, the place where we had built everything. My throat tightened, a burning sensation clawing its way up. I closed my eyes, but the images of our past in that apartment, overlaying the sounds of their present, were a torment. The small kitchen where we'd cooked ramen, the worn couch where we'd planned our future, the narrow bed where we'd sworn eternal loyalty. It was all a cruel mockery now.

I turned and walked away, each step a deliberate act of burying the past. I went straight to the corporate office, my mind cold and clear. The 50/50 partnership agreement, the meticulously drafted document that bound Jax and me, lay on my desk. I picked it up, the thick paper feeling flimsy in my hands. With a savage, almost surgical precision, I shredded it. The sound was deafening in the silent office.

"He'll regret this," I whispered, the words a vow. "He'll regret every single thing."

Later that night, I found myself in the penthouse bar, nursing a single malt. Our mutual friend, Liam, was there, the only one Jax still confided in. I stayed in the shadows, cloaked by the dim lighting, listening. Jax' s voice, slurred but clear, carried across the room.

"Ava's too ruthless, man," he slurred to Liam. "She's just... business. With Ember, I feel human again. She's pure, you know?" He chuckled, a sound that scraped against my raw nerves. "Ava? She could never leave me. She needs this. She needs me."

A cold, hard laugh escaped my lips. It was a sound I barely recognized. Too ruthless? Pure? He still saw me as the ruthless, ambitious woman I had become for us, for him. He didn' t see the girl who loved him fiercely, who had sacrificed everything for our shared dream. He didn't see the broken woman standing just feet away. And he believed I could never leave. That I needed him.

The arrogance, the sheer ignorance of his words, ignited a fire in my soul. My heart didn't just turn to ice; it shattered into razor-sharp fragments, each one burning with a vow. He thought I was ruthless? He hadn't seen anything yet. He thought I needed him? He would learn.

I reached for my phone, scrolling through contacts until I found the one I had kept hidden, the one that represented a past I had always resisted. Jax' s estranged, powerful political family in Washington D.C. The Briggs. He never wanted to be associated with them, always prided himself on his self-made status. But secrets were weapons, and I had just found the biggest one.

"Send him home," I muttered into the phone, my voice devoid of any warmth, any emotion. "He's all yours."

Then, I hung up. The game had changed. This wasn't about love anymore. This was about retribution. And Jax Madden was about to learn just how ruthless Ava Sandoval could truly be. He believed I couldn' t leave? He was wrong. And he was about to lose everything he valued.

Jax's world didn't just crumble; it imploded. My call to his estranged family had been a surgical strike. Within days, he was gone, whisked away by the very power structure he' d always disdained. His attempts to resist, to return to Ember, were futile. He was a pawn in a game far larger than he could comprehend, a game I had just set in motion.

His frantic calls, his desperate texts, were met with silence. I had blocked him. Erased him. The legend of Las Vegas's King and Queen was dead, replaced by whispers of a ruthless Queen who had exiled her King.

I didn't care. The hollow ache in my chest was a constant companion, but it was overshadowed by a burning desire to prove him wrong. To prove them all wrong. He thought I was "too ruthless"? I would show him ruthless.

My focus narrowed to a single point: the complete annihilation of our competitors, especially Gonzalo Harris. The pain fueled me, a dark energy that sharpened my mind and dulled my emotions. I worked relentlessly, sleeping little, eating less. The corporate world became my battlefield, and I was a general without mercy.

Weeks later, the city buzzed with rumors of my ruthlessness, my cold ambition. But no one saw the silent screams beneath the polished exterior, the fragile woman teetering on the edge. The pain was an addicting torment, a constant reminder of what I had lost, and what I had to prove.

One night, the suffocating silence of my penthouse became unbearable. I craved noise, speed, a tangible threat to match the storm inside me. I found myself at an underground street race on the city's outskirts, the roar of engines a balm to my frayed nerves.

"Well, look what the cat dragged in," a sneering voice cut through the din. It was Marco, Harris's nephew, a petty thug who thought he could fill his uncle's shoes. He' d lost a significant chunk of his family' s holdings to me in the past few weeks. "The Ice Queen herself. Come to see how the real world lives?"

I ignored him, my gaze fixed on the asphalt track.

"She probably needs a new thrill now that her little boy toy is gone," Marco taunted, stepping closer. His cronies snickered. "Rumor has it he ran off with a pretty little thing. Left the Queen all alone in her castle of glass."

My eyes slowly turned to him, colder than the desert night. "You're talking too much, Marco."

He laughed, a harsh, grating sound. "Feeling feisty, are we? How about a little wager, then? I bet you don't have the guts to get in a car and race. Not with me." He gestured to a souped-up muscle car, its engine revving impatiently. "Winner takes all. My remaining casinos. Your... reputation. Or what's left of it."

A flicker of something dark and dangerous ignited within me. This was it. A chance to feel something, anything, other than the dull ache of betrayal. A chance to push the limits, to court disaster. "Fine," I drawled, my voice steady. "But if I win, you crawl to me on your broken knees and beg for mercy."

His smile widened, predatory. "Deal."

I slid into the driver's seat of a sleek, black supercar, a loaner from one of my contacts. My hands gripped the wheel, the leather cold beneath my fingers. The starting gun fired. I floored it, the car rocketing forward, a blur of speed and noise.

Then, the insidious realization dawned. The steering felt loose. The brakes, unresponsive. Marco. He' d tampered with the car. A cold laugh escaped me. Of course he had. This wasn't just a race; it was an assassination attempt.

A perverse thrill shot through me. This was it. The ultimate gamble. I pushed the car harder, ignoring the unstable steering, the protests from the engine. The speedometer climbed, blurring the world outside. A sharp curve ahead, leading directly to a sheer drop off the canyon road. My vision narrowed. The pain, the betrayal, the crushing loneliness-it all coalesced into a single, terrifying resolve. Let it end.

The car screamed, tires losing traction, the cliff edge rushing into view. I closed my eyes, a strange sense of peace settling over me.

Suddenly, a violent impact. Another car, a black blur, slammed into mine, forcing my vehicle sideways, away from the precipice. The world spun, a cacophony of screeching metal and shattering glass. The seatbelt bit into my shoulder as my head whipped forward, then back. Darkness.

When my eyes fluttered open, the world was a blurry mess of sharp edges and muted colors. A throbbing pain pulsed behind my temples. My arm screamed in protest, twisted at an unnatural angle. I heard shouts, frantic voices. Someone was leaning over me, their face indistinct.

"Ava? Ava, can you hear me?" The voice was familiar, yet alien. A jolt of something akin to panic shot through me.

Then, clarity. His face. Jax. His hair was disheveled, a gash bleeding above his eyebrow, his pristine suit jacket torn. He looked like he' d been through hell. He was pulling me from the wreckage, his hands gentle but firm. My eyes drifted to his arm, cradling me. A deep, jagged cut bled freely through his sleeve. He was hurt. Because of me.

"You idiot," I rasped, the words thick with pain and something else I couldn't name.

"Marco!" Jax roared, turning his attention to the crowd. He shoved me into the arms of Carlisle, who had miraculously appeared, then stalked toward Marco, his eyes blazing with a dangerous fury. "You piece of trash! You tried to kill her!"

Marco, pale and trembling, stammered, "She cheated! She broke the rules! She deserved it!"

"Rules?" Jax sneered, grabbing Marco by the collar. "You tampered with her car, you coward! You' re nothing but a rat, just like your uncle!"

"He's right, Jax," a soft voice broke through the chaos. Ember. She emerged from the crowd, her innocent eyes wide with fear, clinging to a man who looked suspiciously like her "brother" Harris had mentioned. "Ava... she' s always been like this. Ruthless. She doesn' t care about anyone but herself. She probably had it coming." Her voice was a silken poison, dripping with false concern.

The words slammed into my chest, colder and harder than any physical blow. Ruthless. Doesn' t care about anyone but herself. Jax' s words, echoed by Ember. A wave of bitterness washed over me, clearing the fog of pain. He was still blind. Still lost in her manufactured innocence.

I pushed away from Carlisle, ignoring the protest of my injured arm. "Let's go," I said, my voice flat, devoid of emotion. "I've seen enough."

Jax turned, his eyes wide. "Ava, wait. I can explain." He took a step towards me, his hand reaching out.

Then Ember, with a theatrical gasp, stumbled. "Jax! My head... I feel faint." She swayed dramatically, clutching her stomach. Jax immediately diverted his attention, his arm wrapping around her, holding her close. My gaze fell to their matching, pale blue sweaters-a symbol of their new, pure beginning. A sick sense of irony. He chose her, again. Always her.

Pathetic, I thought, a bitter taste in my mouth. You truly are pathetic, Jax Madden.

I didn't wait for him to explain. I didn't wait for Ember to recover. I just walked away, the adrenaline of the near-death experience fading, leaving behind only the crushing weight of utter, desolate finality.

The world spun around me, a dizzying kaleidoscope of pain and betrayal. My arm throbbed, a constant reminder of the near-fatal crash, but the real agony was a deeper, colder wound. I had to get away. Away from Jax, away from Ember, away from the crushing weight of their betrayal.

"Ava!" Jax's voice cut through the haze, urgent and desperate. He was behind me, his hand reaching for my uninjured arm.

But before he could touch me, Ember let out a small, choked cry. "Jax! My head... it hurts." She swayed, her eyes fluttering.

Jax's hand dropped, his attention instantly diverted. "Ember! What's wrong?" He scooped her into his arms, his face etched with concern. "Someone call an ambulance!"

I watched, a cold, hard knot forming in my chest. He chose her, again. Always her. My injuries, my near-death, meant nothing compared to her delicate fragility. It was a familiar pattern, a cruel echo of his words: "She's pure, you know?"

Carlisle was by my side, supporting me as I limped towards his waiting car. "Just get me out of here," I murmured, my voice raspy. I didn't look back. I couldn't.

The emergency room was a sterile white blur, filled with hushed voices and the rhythmic beeping of machines. My arm was set, my head wound stitched. I refused pain medication. I wanted to feel it all, every agonizing throb, every sharp stab. It was a deserved punishment.

Through the glass of the observation room, I watched Jax pace, his face a mask of worry. Ember lay in the bed, looking pale and fragile, her hand clutched in his. He was murmuring reassurances, stroking her hair. The picture of devotion.

My gut twisted. This wasn't the man I had built an empire with, the man who had seen me as an equal, a partner. He was a doting fool, completely captivated by a lie.

I signed my discharge papers, my name a scrawl of defiance. As I turned to leave, Jax spotted me. His eyes widened, a flash of relief, then concern.

"Ava! You're awake! Are you okay? I... I was so worried." He started towards me, his hand reaching out.

"Don't," I said, my voice flat. I didn't flinch, didn't move. "We have nothing left to say."

"But... Ember, she's..." he began, his voice trailing off.

"She's your problem now," I finished for him, my gaze colder than the winter winds. "Keep her. And good luck."

I turned, Carlisle guiding me. Jax tried to follow, but a nurse gently stopped him, reminding him of Ember's delicate condition. His eyes, filled with a desperate plea, met mine for a final, agonizing moment. I gave him nothing. Just a blank stare, a shattered reflection of the woman he had broken.

I left the hospital, the crisp night air biting at my skin. Carlisle drove me to my penthouse, but I couldn't stay there. It felt too big, too empty, too full of ghosts. I directed him to the old apartment building on the fringes of downtown, the one Jax and Ember had claimed.

The faded brick facade looked even more desolate in the moonlight. I let myself in with the spare key I still carried, a relic from a different life. The air inside was thick with the scent of cheap paint and stale cigarette smoke. They had tried to erase us, to paint over our memories.

A flicker of light caught my eye. A small, framed photo. It was us, young and reckless, laughing on the fire escape, our arms around each other. I picked it up, my fingers tracing the outline of his face.

"Ava?" A voice startled me. It was Mrs. Rodriguez, the building manager, her kind face etched with worry. "I haven't seen you here in ages. Jax... he told me you wouldn't be coming around anymore." Her eyes softened. "Is everything alright, dear?"

I forced a brittle smile. "Everything's just fine, Mrs. Rodriguez." My gaze fell to the date scribbled on the back of the photo: October 26th. Our anniversary. Fifteen years. Today.

Fifteen years, I thought, a bitter laugh bubbling in my throat. And he forgot. Or maybe, he just didn't care.

"I just came to... retrieve a few things," I lied, the photo still clutched in my hand. I needed to leave. Before his "muse" returned.

As if on cue, the door creaked open. Ember stood there, looking surprisingly vibrant for someone who had just been in the emergency room, her eyes narrowed as she took in the photo in my hand. "What are you doing here?" she demanded, her voice losing its innocent lilt. "This is our home now."

"Our home?" I echoed, a cynical smile playing on my lips. "Funny, I seem to recall building this place from the ground up with someone else." I leaned in, my voice dropping to a low, dangerous whisper. "You should be careful, little girl. Some foundations are built on solid rock. Others," I gestured around the peeling apartment, "are built on quicksand. And when they crumble, they take everything down with them."

Her face flushed, her eyes blazing with a sudden, unexpected fury. "You think you're so smart, don't you? You think you can just waltz back in here and ruin everything? Jax chose me! He loves me! He wants to start a family with me, a real family, not some cold, calculating partnership like yours!" She clutched her stomach again, a calculated gesture. "He wants a baby, Ava. My baby."

The words hit me like a physical blow, stealing the air from my lungs. A baby. Our dream. One we had spoken about in whispered tones, planned for a future that now seemed impossibly distant. He had promised me a family, a legacy. And now... with her.

My mind reeled, a torrent of memories flooding my brain. The fertility treatments, the countless doctors' appointments, the quiet tears I cried in the bathroom when they told me it might never happen. Jax had held me then, comforted me, promised me it didn't matter, we were enough. Lies. All lies.

A cold, hollow laugh escaped me. "A baby?" I repeated, the word tasting like ash. "How... convenient."

Ember' s eyes flickered, a hint of something calculating in their depths. "He loves me," she insisted, her voice trembling, but the conviction was gone. "He loves our baby."

I looked at her, at the lie shimmering in her innocent eyes, and then at the photo of Jax and me, young and full of hope. The contrast was stark, brutal. The pain was so profound it almost felt like peace. It stripped away all pretense, all hope, all lingering affection. There was nothing left but a burning, icy rage.

"Keep your baby, Ember," I said, my voice barely a whisper, yet infused with an unmistakable threat. "And keep him. Because from this moment on, you both are dead to me."

I tossed the photo frame onto the worn wooden floor, letting it shatter. The glass shards reflected Ember's terrified face, a fitting mirror for the wreckage she had caused. I turned, walking out of the apartment, out of that building, and out of that life. I didn't look back. The rain began to fall, cold and relentless, mirroring the storm raging inside me. I was done.
