I am in the same position, except my husband hasn't been there for me. The only way I've been able to stay in this marriage is denying me needs. We are in a sexless marriage, but not because of me! I desire intimacy very much, but he doesn't. He wont't go anywhere with me, and because he had a small business that didn't do well, I have supported us for the last few years. But it is difficult to walk away from 25 yesrs of marriage without trying to fix it. I've tried, but he doesn't seem willing. I am seeing a therapist to work through my issues and hope that it helps. I am also doing a 12 step group because I was raised in an alcoholic home. This helps alot. Take care you guys! You're not alone!
