Chlorine and Regret

Marta stood at the hotel room vanity, staring at the amber bottle in her hand. Vitamin D, the doctor had prescribed—something about northern winters and seasonal depression. She swallowed it dry, catching her reflection in the glass: forty-three, faint lines around eyes that had seen too much, lips still full but pressed thin by years of compromise.

Down at the pool, Marcus was already swimming. His strokes cut through the turquoise water with athletic precision, each movement practiced and efficient. Marta watched from her balcony, her palm sweating against the railing as she gripped it too hard. They'd come to Cabo to fix whatever had broken between them, but six days in, she wasn't sure anything could be repaired.

The memory of his confession still burned: an affair with a colleague, twenty-six and brilliant, everything Marta used to be before motherhood and mortgage payments and slowly disappearing into the background of his life. He'd sworn it was over. He'd sworn he wanted to make this work. She'd agreed to the trip because she didn't know what else to do.

Marcus pulled himself from the pool, water streaming from his body like he was being reborn. He waved up at her, that familiar smile that used to make her stomach drop in the best way. Now it just made her tired.

She'd started taking the vitamins because everything else felt out of control. She could measure her health in daily doses, could track something concrete in a life that had become a series of grey compromises. Swimming had become her anchor—the one place where her body still felt like hers, where the silence underwater gave her permission to not be Marcus's wife, anyone's mother.

Her phone buzzed on the nightstand. A text from her sister: "You don't have to stay."

Marta's palm pressed flat against the balcony railing, fingers spread wide. She looked at Marcus toweling off below, at the palm trees swaying in the breeze, at the endless blue horizon that seemed to mock her with its promise of something beyond this moment, this choice, this life she'd built and somehow lost.

She turned from the railing, grabbed her suitcase from the closet, and began to pack.
