I almost fainted when I saw photos of them together, hugging and kissing. My hands shook, but when she returned, I acted like nothing had happened and kept chatting as usual.

That night, I confronted my husbandIn tears, he admitted the affair began a few months after I gave birth to our daughter. He said I’d seemed so preoccupied that he felt neglected.I’d known my friend since we were 14. She always copied me, even dated two of my exes. I thought it was just teenage behavior. But clearly, she wanted my life—even as adultsI divorced him, took my daughter, and moved to a new town. Looking back, I’m grateful I found out. As for the two of them? They separated two weeks after I left.
