My husband spent 3 years fixing my sister’s sink until our daughter exposed him.

I took a deep breath and looked through the kitchen window.

They weren’t working on any plumbing. There was no toolbox in sight.

Instead, there was a bottle of expensive white wine on the counter. Mark and Karen were sitting at her small kitchen table. He was holding her hand, laughing at something she said. It was a genuine, happy laugh. I hadn’t seen him laugh like that in years.

Then, he leaned over and kissed her.

My body went completely rigid. I felt a physical sickness rise in my throat. I wanted to scream, to kick the door down, to break the glass. But something colder and calmer took over.
