Thank you for the toughtful response PM. My additional thoughts:
Principled Man wrote:Without solid evidence or a professional diagnosis there is no way you telling her about your speculations is going to drive her to therapy, especially while you are in therapy. Be prepared for blameshifting: you are the crazy one. Not to mention that if she does not cheat or handle advances well, this is a pretty consistent theme in the HPD universe. There might be something else going on: BPD? As a lay person you probably can't say. All you can do is watch her behavior and decide in advance what you are willing to live with.
Yeah, i was afraid someone would say that me bringing it up would get that kind of response. Re: cheating, my thought is that her past traumatic experience has set a boundary for her in that regard. It gives my hope that me setting firm boundaries on what I will or won't put up with can help lead to things getting straightened out. She is still an overtly sexual and flirtatious person as described by pretty much every HPD description, but i can't say it bothers me b/c I am not insecure in that regard and I do trust her on that topic.
Re: BPD, i read up no that some but came to a quick conclusion that HPD was what I was dealing with. I will check on that again though.
If she can't see it, she can't see it and no words, discussion, argument, or evidence will convince her otherwise. From what you've written I gather arguing with her is an "escalating" and "manipulative" affair. She will be convinced by your actions, not your words.
Arguing is definitely an escalating and sometimes manipulating affair. Does a Socratic approach pay any dividends? For example she brings up as a point of distress that some members of my family don't approve of her or don't seem to like her and that her's love me. Instead of trying to explain how her behavior has created that situation, should I ask questions that lead her to see the different ways I have presented myself to her family vs how she has presented herself to mine? It sounds like the only thing that works for a HPD is self-discovery and I'm trying to think of ways to make that happen.
So I take it that at this point divorce is not an option. Make it one in your mind. What are you willing to tolerate, and what are you not willing to tolerate. What are your non-negotiables when it comes to her behavior? What are the consequences when she transgresses. It's up to you to show her the effect she has on the world by not putting up with bad behavior. There must be consequences. Telling her she has HPD will accomplish little, and might even provide fodder for excusing her bad behavior. Treat her like any other person, PD or not. When she does things you don't like think, "what would I do if my best friend behaved this way? How would I react? Would I continue to pardon, placate, and try to please this person?" Continue with your therapy, work on your self, discover your boundaries and defend them. Look for posts on here by Tatteredknight. Check out the book "No More Mr. Nice Guy" and there is a very helpful forum for guys in situations similar to yours based on the psychology of this very helpful book.
Divorce is an option, but I feel like I owe it to myself and my vows to try everything I can think of to solve this first. The problem with this is that I am confident ni my own abilities to handle A wide range of things and sometimes bite off more than I can chew. This led to me trying to manage the relationship for a good 5 months, which ended in my own personal emotional mini-crisis. It disgusts me to think of it. My therapy has definitely helped me with solving the Me part of the problem.. I will check out those things you referenced.
