Alex: I'm going to give it to you straight: You will never be truly happy with this woman unless you are willing to be celibate. She will not change.
I married my intellectual match. We love each other and really enjoy discussions, reading, etc. We're both lawyers and have a lot in common.
Except for sex. It was fine at first, dwindled before we got married, and is almost non-existent now. I had sex twice last year. Nothing in 2004. Me bringing it up causes no end of turmoil. But I continue to bring it up. I shared the book with her, and she went ballistic. She's read very little of it, and, as I predicted, has read the part about HD partners in order to show me how I'm doing everything wrong.
It's an uphill battle. My advice is to try to keep her as a friend, and get a new woman who your intellectually, spiritually, and physically in sync with.
Good luck
Hairdog, who, predictably, had a fight with his wife this evening...after all, it's the beginning of the weekend and she needs some reason to reject me, right?
