Falling for my Husband's Rival

Sarah's POV

I rushed into the restroom, slammed the door shut, and barely made it to the sink before I threw up. My knuckles ached as I gripped the edge of the sink.

Am I dreaming? No.... no, I'd held it in my hand just a few minutes ago, a black credit card, t'was cold, and heavy. The name written on it in gold letters were clear; Sean Miller.

A loud bang on the door pulled me out of my twisted thoughts, followed by Ms. Harlow's yell. "What the hell are you doing in there?" She slammed her fist against the restroom door repeatedly, the sound echoing through the small space like a heartbeat.

I glanced at the door and sniffed my runny nose. "Just a minute, please," I said, my voice almost cracking. I leaned over the sink, staring at my puke inside it, my eyes brimming with tears. I squeezed them shut and forced myself to breathe through my nose.

The stranger's voice came echoing carelessly in my head again, "No, darling, I'm just living life... Sean's wife died years ago. She'd been lucky to be with such a loving man before she died."

Dead? He told her I was dead? The thought hit me like a punch, and my stomach twisted in protest.

"Get the fuck out of there, bitch! You have a customer waiting, Sarah! We don't pay you to hide in the restroom!" Ms. Harlow screamed, and banged the door harder this time making me flinch.

I turned on the tap, washing everything away as fast as I could. Water splashed on my hands and my uniform but I didn't care, my heart was pounding too loudly to think. I wiped my face with the back of my hands, and unlocked the door to see Ms. Harlow standing there, arms crossed, and heels tapping impatiently against the floor.

Her sharp eyes scanned me from head to toe before she snarled, "You look like shit! Fix it! Customers don't pay to see your problems."

I felt her words slice through me, but I kept my head down, eyes burning.

Fix it? How? By pretending I'm fine when I'm falling apart?

"Get going!"

She stepped aside, and I walked past without saying a word, her gaze dragging over me, face twisted in disgust, like I was something dirty.

I walked back into the sales area, and the lights hit me instantly, too bright and clean. Everything was shining... polished floors, and glass shelves lined with dresses worth more than my rent.

The stranger was still there, standing by the counter, flawless as ever. Perfect hair, perfect makeup, and a smile that didn't know what hunger felt like. She was still on that call that was driving me insane.

She laughed softly into her phone. "Well... just shopping for our vacation tomorrow," she said, pausing for a few seconds as she listened to whoever she was speaking to. She winced, "Why not? Yeah, life's good with Sean."
