Dear Prudence,
I’m a 34-year-old man, and seven years ago, I made the horrible decision to cheat on my wife. At that point, we had been married for three years, and she quickly filed for divorce after she found out. We went to counseling, worked out our issues, and managed to reconcile and stop the divorce. Since then, we’ve had two kids. Despite the guilt I still feel, I’m happier than ever.
Last week, though, I found out that in the brief time my wife and I were separated following my affair, she entered a relationship with a male coworker and caught an STI. They broke up once we got back together, and I don’t consider it cheating. However, I now have the STI she caught from him. She refuses to accept that she caught one, and thinks I’ve cheated again! What should I do?
