I went looking for the other woman. I never expected to find her sitting at our wedding, smiling in the front row, knowing the whole time.

It was just a kid's prank, lifting the second phone to spy on grown-up calls. Until one afternoon a familiar voice asked my mother what she'd cooked.

My husband automated his life down to the minute. One scheduled text on the wrong day told me everything he had been hiding for two years.

He deleted the app, cleared his history, covered every track he could think of. He just forgot the one inbox we had always shared.

I woke at 4 a.m. certain of something I had no proof of. By breakfast I had the proof, and I wished I'd never gone looking.

My team works remotely, so I live inside our chat app. One Saturday, half-asleep, I noticed a colleague go active at 4 a.m. Then I noticed who else did.
