Hi Hope. I don't have a success story, but I am going through a similar situation with the intimacy issues. Due to a childhood of sexual abuse, I had a ton of them. Now that I'm working through that, my H doesn't want the intimacy either as he thinks I'm only doing it for him.
I can tell you that I have been DBing since January and dealing with this since October and he is still with me. Separated in the same house, but not any further. Sandy's rules are sooo important. If I show any sign of pursuit, he backs off quicker than at mosquito avoiding your hand.
I'm sorry that you are on here, but it really will help you out.
