My husband dated a girl that is friends with people in his friend group so she is invited to parties. One of the groomsmen's has a daughter who is turning one in March and we are invited to her birthday party, but my husband's ex is going to be there. We have gone to dinner once with her there before and I felt so uncomfortable and my husband said everything felt real awkward because I didn't really talk the whole night and it was obvious I didn't want to be there. My husband has told me numerous times she is crazy and that's why they broke up. She is also the girl he slept with when we briefly broke up and he kept that from me for about a year. She apparently had been under the impression they would get back together instead him and I got back together two weeks later. When we went out to dinner before she had a boyfriend, but she is single. She also messaged him on our honeymoon congratulating him, but during that conversation she mentioned how she's now single and how he was such a great boyfriend. I am just so uncomfortable around her. I think part of it is he is the only guy I have been intimate with. He has been intimate with other women, but she's the only one he was actually ever in a relationship with. The rest were just girls he hooked up with. My husband thinks I need to get over it since he obviously married me and not her. Am I Wrong for not wanting to be around her?
