Dear Prudence,
I am a divorced mother who’s now back in college. My divorce was nearly three years ago and one of the best decisions I have ever made. I recently learned that my ex-husband (and the father of my children) has been seeing a woman. I think that’s great, and I want him to be happy. The problem is that she is a fellow student in one of my classes. When I realized the connection, I started bawling on the way home from class. I hope so much that she doesn’t know who I am—but even more than that I am beside myself with sadness, and I don’t know why. I still care deeply for my ex, but I’m currently in the best relationship of my life with a wonderful man. Why am I sad? Why does knowing who she is bother me so much? How do I heal and continue? My marriage was abusive and tumultuous, and I’m so happy with my new relationship, so how is this even an issue?
