Husband gets way too sensitive about my sexual history

My husband and I were 39 when we met, so both had a few broken relationships behind us. We're 41 now and, for the most part, our relationship is excellent. However, he's very sensitive about my romantic and sexual history.

- Dear Coleen

I had a lot of short-term relationships and my fair share of casual hookups. In fact, I never had a serious long-term relationship, but it’s not because I didn’t want that, it just never happened for me.

He, on the other hand, had two serious girlfriends before he met me. Both women cheated on him, which ended the relationships, so I get why he’s maybe a bit insecure.

Whenever we argue, he finds a way to bring up my past and throw it back at me. A couple of times he’s said: “You don't know how to be in a relationship because you've never had one”.
