Recently I broken up with my gf/fp due to the fact that i keep hurting her and it started to get bad to where we were arguing every single day but for extremely small reasons (btw this is my first relationship) . I was recently diagnosed with bpd and it’s explained everything but what im getting at is that the day after i broke up with her she was in the bed with her guy best friend. Now im overthinking and want to hang myself. NO MORE RELATIONSHIPS FOR ME EVER AGAIN!
