My ex boyfriend is in the same friend group as me. We don’t see each other often as I hang out with the girls and my ex is friends with their husbands. My friend asked if I minded if my ex is invited to a Halloween party because her husband felt bad leaving him out of invites. I told her to go ahead. My current boyfriend (7 months) said he does not want me to go if my ex will be there. My ex and I dated for about 8 months and it was a mutual breakup. There’s no residual feelings and we don’t see each other much, but do from time to time at group events. I told my boyfriend I still wanted to go to spend time with my friends, and he said that be me going I was being disrespectful to the relationship and inconsiderate. I also invited my boyfriend to the party before I knew my ex would be there and he didn’t want to go. My boyfriend said if I went to the party he would end the relationship.
As soon as I knew my ex would be invited, I told my boyfriend.
I care about my relationship and there’s a lot of good things about it, but I feel he is being unreasonable.
TL;DR: boyfriend doesn’t want me going to a party my ex boyfriend is at. I still want to go. What do I do?
