Sounds to me like she has the who wants to want syndrome. People that grow up under dysfunctional conditions like she did essentially create lots of barriers to protect themselves. Essentially everyone that SHOULD have been important to her caused her great pain. Her reaction is to do what is necessary to prevent this pain, so she makes herself hardened. She does NOT need others, her masculine polarity is way to high, and her femminists beliefs tell her that she can do it on her own. She can no longer trust anyone, and she sees you as untrustworthy because she believes that you will also hurt her.
I see the same thing in my own wife. Now if I just knew how to SOLVE this problem.
Hey, what is happening in your marriage counselling? I would love to hear about it. Is it worth it? Any real success?
