Fiancé's Affair Shock: Leaving Love Behind

The laughter from my bachelorette party still echoed in my ears as I fumbled with my keys at the front door. Ashley had insisted on champagne toasts at three different bars, but all I'd wanted was to come home to Preston. Tomorrow would change everything—in less than twelve hours, I'd walk down the aisle and become Mrs. Preston Taylor after eight years of building our life together.

I slipped off my heels in the entryway, sighing with relief as my feet touched the cool hardwood. The house felt different tonight, charged with anticipation. My wedding dress hung upstairs like a promise, and our packed honeymoon suitcases waited by the bedroom door. Everything was perfect, exactly as we'd planned.

"Preston?" I called softly, not wanting to wake him if he'd fallen asleep on the couch again. He'd been working late all week, tying up loose ends before our two-week honeymoon in Italy. "I'm home early. I just wanted—"

The words died in my throat.

There, on our couch—the same burgundy leather sofa where we'd spent countless evenings watching movies, where he'd proposed two years ago—Preston was wrapped around another woman. His hands tangled in long dark hair, his mouth pressed against a neck I recognized with sickening clarity.

Bella.

Time fractured. The world tilted sideways, and I gripped the doorframe to keep from falling. My engagement ring caught the lamplight, the diamond that had once symbolized our future now feeling like it was cutting into my finger.

They hadn't heard me come in. Preston's shirt was unbuttoned, hanging open, and Bella's dress was pushed up around her thighs. Her legs were wrapped around his waist, and the soft sounds they made—intimate, desperate sounds—carved something hollow inside my chest.

I must have made a noise, a gasp or a sob, because they broke apart. Preston's head snapped toward me, his eyes wide with something that might have been surprise but wasn't shame. Bella turned too, her lips swollen, her hair mussed, and for a moment she looked almost triumphant.

"Jessica." Preston's voice was steady, casual, as if I'd just walked in on him reading a book. He didn't scramble to button his shirt or push Bella away. He simply looked at me with those gray eyes that had once made me feel like the only woman in the world.

"What—" My voice cracked. "What is this?"

Bella slid off Preston's lap with deliberate slowness, smoothing down her dress. "Jessica, we didn't expect you back so early." Her tone was almost apologetic, but there was something else underneath it. Relief, maybe. Or victory.

"Eight years." The words came out as a whisper. "Preston, we're getting married tomorrow. Tomorrow."

He stood up, finally buttoning his shirt with methodical precision. "Jessica, you're overreacting. This doesn't change anything between us."

Overreacting. The word hit me like a physical blow. "Overreacting?" My voice rose, shrill and desperate. "I just found my fiancé with his sister the night before our wedding, and I'm overreacting?"

"She's my adopted sister,"
