I still have issues with abandonment, being touched, having someone in the same bed. I do sabatage my relationships because I don't want to be hurt again. Lots of breakup/makeup, rollercoaster, high drama.
I think I do make poor choices just so I can say they're all the same, excuses, playing the victim. Tell myself never again, but falling for the same thing each time. I'm good at "you're better off without me".
I don't think I meant to hurt my luvie on purpose; only because I felt they don't care. Like I meant nothing to them. Never thought of cheating though, but always wonder if my partner is faithfull. Constant affirmation needed, being wanted. Real "clingy".
I think it's great that you want to be friends still, but it can be emotionally draining. Good luck
