It seems to me that my H's inability to have and maintain friendships is a major difficulty in our R. Like yours, H uses other people's issues and concerns to measure his own situations.
I think that in my case H ends up looking for friendship at work among the women in the workplace. This is a recipe for disaster, if you ask me. Of course, women are easier to talk to ...and he does not feel competitive with them. But then, he starts getting a bit too close....
ugh. What is the solution? Have you thought of any? Does NG notice that he has few friendships of his own? If so, does he see this as a problem?
Let me know if you figure out some strategies here that work for you. maya
