<human>: My ex and I dated for a long time. It ended really badly. I got a new bf right away who I love and is a way better match for me. That pissed off ex a lot. We haven't spoken in over a year and I know that is the best thing. We had a lot of mutual friends over the years. The friends will talk about him sometimes which I really don't like but I just go with it because I [thought] I was over him and I don't want to sound like I get hurt when he comes up. It just usually catches me off guard and I don't like thinking about him. 

My best friend in the world was at a music festival recently and saw ex randomly. My best friend felt extremely uncomfortable. She was there with her bf and my ex bf said "My new gf is in the bathroom" Obviously best friend told me this which I wish she wouldn't have. As much as I didn't want it to affect me, it just kind of pissed me off because I feel like he probably just said that to her so that it would get back to me. I mean, isn't that kind of weird to just randomly say your new gf is in the bathroom without being asked? 

My questions: 1.) do you think the ex said that just so it would get back to me or was it an off handed remark that I'm probably reading too far into 2.) Is it weird of me to feel bad about this? When best friend told me over text and I read it, it was hard to concentrate on what my friend next to me was saying and I was very taken aback. I would like to think I'm completely over ex after so much time but could this be a sign I'm not? Any suggestions of next steps I could take to feel better about this situation would be greatly appreciated.

Give me the gist of the text in a nutshell
<bot>: my friend told me news about my ex bf that caught me off guard and made me upset. What should I do next now?
