Search Results: get back with ex

My boyfriend of 4 years, relatively a good and loyal man. He has a group of friends since high school. Two of them got married (guy and a girl) but divorced. Anyways the girl texted him asking if he remembers a concert in which they all went to way back in high school to which he responded with yes I do remember. She said oh so and so didn’t remember you being there and he responded with I remember a lot of half naked girls dancing on stage and kass saying to me “did you get a chubb watching that” to which i said I lowkey did. I was immediately offended and heartbroken to why he would mention that memory to her and it was entirely inappropriate. I mentioned to him and he said I understand why you would be upset I’m sorry I was just remembering a memory and it was a long time ago we weren’t together and I said not the point it’s the fact that your mentioning this to your female friend and he said she’s my best friends ex wife and my bestfriend I don’t look at her that way. To which I stayed silent and he asked if this was “resolved” I said I don't know I’m bothered and that’s it. Am I overreacting?
