I had a long reply typed up, but I lost it, so I'll keep this short:
* The principles I learned here and in therapy for taking care of myself and also coping with an addict's behavior also happen to work quite well for dealing with personality disordered people.
* It still really surprises me when I realize that I am willing and able to put up with crazy behavior far more than a normie would. Even after all this personal work. It makes me question how other people live, and how easy it must be to have relationships by comparison. Is that crazy?
