I just don't understand, my girlfriend is very supportive and is always there for me and everything, but I STILL feel insecure, I still feel anxiety that she'll lose interest eventually, or she's find someone else. I think back on all the nice things she has done, but that doesn't take this feeling away. If I get reassurance I feel good for a few days but that's it. I just want to enjoy my relationship! Is this bpd??
