MamaBear, Catching up on your sitch, just wanted to share that my story is quite similiar. My H BEGGED me for more sexual attention for years, and I would try to be what he wanted, but it never lasted, I really wasn't that into it, low self-esteem, poor body image, depression. Long story short, I was shocked when H and I started "working on things" that he wasn't that interested in sex. Why? MAJOR affair guilt, anger at me for rejecting him, and not believing that I was genuinely interested in him, in a sex life, in passion, he thought maybe it wasn't genuine change.
My point is that as we have become closer as friends, and some of the non-sexual intimacy returned, his drive and passion returned as well. So, I guess I am conferring with GH, maybe it is too soon, you told him where you stand and what you are wanting, give him the space to rediscover those feelings again. And, of course flirting and being sexy helps too!
