After My Husband Replaced Me with His Mistress at Work

The humidity in the Hamptons always felt heavier than in the city, like a wet wool blanket draped over the manicured lawns of the estate. I adjusted the strap of my white silk slip dress, forcing my posture into the rigid verticality I’d practiced in front of a mirror for five years. My feet throbbed in the Jimmy Choos—a secret rhythm of pain hidden beneath the floor-length hem—but my smile remained fixed, a porcelain shield against the vultures of high society.

"The scalability of the new interface is actually its strongest asset, Mr. Sterling," I said, my voice pitched to that specific, soothing frequency that made powerful men feel heard but not challenged. I gently touched the stem of my untouched champagne flute. "Atlas isn’t just building a platform; he’s building an ecosystem. The IPO is conservative compared to the projected Q4 yield."

Arthur Sterling, a man whose skepticism was as legendary as his portfolio, finally softened. The deep furrow between his brows smoothed out. "You make a compelling case, Mrs. Webb. Atlas is lucky to have a wife who actually reads the prospectus."

"I do more than read it," I thought, but I only dipped my head in a demure nod. "I just believe in his vision."

As Sterling wandered off to find the bar, the tension in my shoulders unspooled. I had done it. I had smoothed over the PR disaster from last week’s leak and secured the anchor investor. I scanned the sea of white linen and diamonds, searching for my husband.

"Sterling is on board," I whispered, leaning in. "He wants a meeting on Tuesday."

Atlas didn’t look at me. He kept his eyes on James Richardson, who was mid-anecdote about a yachting mishap in Greece. "Great. Thanks, Maddy," he said, his tone dismissive, like he was thanking a waitress for refilling his water.

"I thought we could celebrate? Maybe grab a—"

"Not now, babe," he cut me off, finally glancing down with a flash of irritation in his blue eyes. "The boys and I are heading to the cigar lounge. Go mingle with Mother. She’s over by the hydrangeas."

He peeled my hand off his arm and turned his back before I could respond. The rejection stung, sharp and familiar, but I swallowed it. That was the deal. I was the support staff; he was the star.

I needed air. The perfume in the main tent—a suffocating blend of Chanel No. 5 and old money—was making me nauseous. I slipped out a side exit, moving toward the stone terrace that bordered the private club rooms. The ventilation from the cigar lounge hummed nearby, pumping out thick clouds of tobacco smoke into the night air.

I leaned against the cool stone
