Yep, HD woman here with a soon-to-be wasband. I don't post much here, since my SSM is soon to be over. But I had to chime in and let you know there are plenty of us HD wives on the board!
#2 of the 3 factors you posted completely applied to my marriage. My H made me the center of his life and was proud, but I think also threatened, by my professional achievements. As I grew professionally throughout our relationship, I think he progressively felt more and more insecure.
What I'm looking for in a partner now is someone who a) enjoys sex ; b) isn't threatened by me; c) has a life and identity of his own, but who enjoys spending time together; d) ... did I say "enjoys sex" already?
Great thread, can't wait to hear what some of the wise HD women on the board have to say...!
