I can honestly say I really feel what youre saying here, and as a BPD male, I can say I have done that and acted that way, however I did it because I was extremely uncertain that my S.O. was actually emotionally 'there' for me.
The flags were everywhere, but we had amazing chemistry, so I knew if we could get communication up to par, then we would be great. She was always so numb and distant, so when we would go months without any talks about us or stuff going on with us, I really started to act out, but I truly did it just to get literally aaaaany reaction from this woman. Like I know it sounds messed up but there was just nothing going on. No sadness, no anger, nothing. She never wanted my help with anything, not even if she needed the help, and she would almost go out of her way to avoid me doing stuff for her, kind of annoying tbh. Just let me be nice? Wtf?
Anywho regardless of what happened between her and I, justified or not, thats basically how I acted from time to time. That being said, had I been convinced she was serious about us, I really do believe my demons would have been calmed. Eh, who knows though.
I really feel like everyone is just becoming more and more convinced that r-ships just literally do not work, and every next r-ship that goes badly convinces them that much more abd makes it that much tougher to get through to them.
If you really love them you literally just have to stick around.
