I have no idea if this will make sense because I have a hard time conveying my feelings, but I'm going to try my best. My significant other follows 3 of his exes on Instagram. When I found out, it did make me insecure and my anxiety went crazy. But over time, I was able to manage it and make peace with 2 of them since they've been friends for a long time. However, with the 3rd ex, I would randomly get anxious and insecure from time to time. I think this is because she was his most recent ex and the one he lost his virginity to.
Anyway, it got to the point where I felt like I needed to talk to him about this again because it really sucks to go from being okay to randomly having these insecurities pop up. He offered to unfollow her and I told him that wasn't necessary because I really didn't want to come off as controlling/pushing him to do something. He told me he really didn't care because he only knew her for 3 months anyway then he ended up unfollowing her. Although I appreciate him coming up with a solution, I can't help but feel incredibly guilty and upset with myself. I expressed to him how I feel like I should've been able to deal with my insecurities alone and if not, then maybe we weren't a match. But he told me he honestly didn't care and he knows where to draw the line (like he wouldn't have offered to unfollow his other 2 exes since they're good friends). That made me feel a little better because I know I didn't demand/force him to do anything, but I still feel like crap because I couldn't get a handle on my anxiety and insecurity.
