I'm feeling lost and unwanted because we have no sex life

I was exposed to porn at a young age, I found my father's stash and I liked it. Most of the men I got involved with also enjoyed porn. I didn't start to feel betrayed by my partners viewing porn until about 5 years ago. Since then porn has lost it's luster for me but I've tried to be patient and understand with my partners for their use of it, because I understand the no expections relief it offers them. It thrills me that my husband has made the choice to try to kick the habbit himself. I try to be supportive and nonjudgemental when we talk about the issue, but I know he hides his usage of it from me because he admits that he still looks at it a couple of times a week. We have good communication skills, so I feel guilty coming here and asking for prayer, but I'm feeling lost and unwanted because we have no sex life. I understand his issues and there are several other factors besides the porn (bi-polar being a huge part of it too). I know he's hurting but he doesn't even want me touching him and this kills me because I'm a very touch oriented person. I've gotten to the point where I don't even try to kiss, cuddle, or initiate sexual relations with him because I'm afraid of being shrugged off. He isn't being ugly with me when he does it and he knows how I feel cause we have talked about it, but he is unable to overcome these issues that prevent him being intimate and I am finding it hard to keep a positive attitude and feel that I am starting to slip into depression again.
