Input: OKAY so about a month ago I reconnected with an ex from a few years back after we bumped into each other on Tinder. Since then I have invited him out on three different occasions to hang out with some of my friends as we all got along very well back in the day. Everyone had a great time and it was entirely platonic as far as I knew. 

On the first night of hanging out we both discussed our deep lack of interest in each other sexually, as well as our recent sexual endeavors with others. I also mentioned that I was in an exclusive sexual situation with another one of my friends and was very much enjoying it. He seemed supportive and I figured that meant we were just friends in his eyes and all was well. 

This past weekend I invited my ex to come hang out at a bar with my usual group, as well as the guy I am boning. Everything went on fine as usual and my ex offered to drive my roommate, my dick appointment, and myself back to the apartment. He has always offered to drive us home in the past and never comes in to hang out afterwards. While we were waiting for the other two to use the bathroom and close their tabs, I mentioned offhand that the other guy was my fuck buddy because he’s real cute and I like telling people (i’m annoying). Upon mentioning this, things took a turn. He got very offended and said that he wouldn’t have offered to drive us home if he had known it wasn’t going to end with him and I “doing stuff”. First he said some very unkind things about my friend but then ended the night by saying “It’s ok that you’re doing that stuff, I just didn’t expect to be so sad about it”. 

Now I feel like a giant asshole but my roommate says I’m not. I’m just trying to decide if it’s worth reaching out and apologizing.
