I believed my husband was simply helping my sister with her house. Then I noticed his story wasn’t adding up. When I followed him one Friday, I finally understood why.

The crack in the facade came on a Tuesday evening while we were clearing the dinner table. Our daughter was helping stack the plates, moving quietly between the sink and the dishwasher. She stopped with a glass in her hand and looked up at her father.

“Daddy was at Aunt Karen’s house again,” she said casually, as if mentioning the weather.
