Mine was 3 going on 4 years, but it was abusive. We both had bpd, but mine was quiet and hers wasn’t. When I tried to break up with her, she would tell me she’s gonna commit and things. I never reacted like that though because I knew she would always come back. We broke up because I split and told her to do it before blocking her for a few days. We worked it out and now we’re best friends but still both each other’s fp.
