So I've been dating this girl for 4 months now and it's great. Passed every shit test we get a long really well. Basically this weekend she mentioned her ex and it didn't bug me. Then we were driving home from a great weekend and were talking about climbing trips. She mentioned her ex fell on this route that had a rating which is higher than anything I have ever done. I got a little pissed and we got into a small argument about it. It made me insecure and I have never been insecure with anything else in our relationship and am not controlling by any means cause I don't care. We talked about it and I was upfront which is prolly not the best call. Basically saying that it is stupid that it did but it fucked with my head. She was saying " I love you and if I cared if someone was better than you at a sport we wouldn't be together". We talked it through and it was a momentary slip up on my end and it was such a beta thing to do. Basically, I just want some opinions on if I can recover from it or should I just call it quits. I mean, I really like this girl but fuck I feel like it's just gonna taint our relationship and now she sees me as a bitch. She has all the qualities of an ideal partner and I can't stop my mind from feeling like a single moment like that is gonna fuck up our relationship long term.
