anyguy,
I concur with airbornedoc on all counts. I agree by being here I sometimes feel "let down", like I still should not be here. Let me share a little about how I've managed to "break free" from HPD madness, but not entirely--kind of like your situation.
4 months ago, I busted her cheating. I thought she was Narcissist or BPD, but she told me after we broke up she was diagnosed HPD. AHA!! Had no contact for 3 months. I contacted her 2 weeks ago because I was curious about whether her therapy was doing her any good. Yes, that was a big risk!
WHY did I contact her knowing what I've learned??!! I am almost finished with my OWN therapy. This girl unleashed so much havoc in my life I needed to get some help. I'm very much emotionally unattached, although I still have fantasies that she will have a break through in therapy and "get it" so to speak. And, like you I've grown very curious about this disorder and why it captures certain people like you and me and others here on the forum.
But to break free emotionally and stay free is not easy without doing the following: Getting a life, so to speak. I'm defining myself better by what I LIKE, not what others want me to like. I'm associating with positive friends and I'm open to dating (finally ready), so I'm talking to women again (without fear) and keeping busy. Since I've been in contact with my exHPD, she's clamping hard on "getting me back", I'm keeping an emotional distance and not letting her dictate anything--she has been told, no relationship unless she gives up her fan club. She says she won't and that I'm insecure. I say she's still a mess and has eons to go in therapy, so she can dream on about me. Please do not beat yourself up over this. This is a process and some people, like myself, have to go through this to get to the other side and be healthly, happy and strong. Spend time thinking of her "bad" side and about good things in your life and slowly you will recalibrate your thinking!! Be well!!
