Thanks, Corri. This is basically what I've been doing. I've been practicing the "no pressure" approach, I've told her in the past what I want. If she asks again, I'll tell her what I want out of the marriage, but I'm done nagging and criticizing her.
Someone on some thread (sorry, can't remember) said, "if you lived in a world where sex didn't exist, how would you rate your marriage?" I'd rate it pretty darn high. Hopefully, she will come around. I'm doing my best to "draw her" back to me, so that she will be attracted to me sexually as she once was.
Thanks again Corri for the advice. It's always good.
