Having dealt with a BPD subhuman in my own life, I noticed that in myself. They really are the scum of the fucking earth and should be euthanized just for being contagious. I have to pay attention to and curate my thoughts now and that's really fucking draining. I miss the freedom of the person I was before I was in that relationship. Definitely in a worse place now, but only insomuch as I have to think about my actions, when being normal and well-adjusted used to be easy and natural. I don't know if I "fixed" the intrusive thought processes that cunt projected into me, but I don't feel good about the idea ever letting my guard down now.
Never give BPD or Borderline people a chance, they absolutely will destroy you, and in ways you may never have considered. Fuck em.
