There's a lot in this post that I'm sure others will respond to better than I can, especially about how disrespectfully your husband has treated you. But I just wanted to reassure you that many people aren't that interested in sex, so please don't feel bad or wrong in any way.

Sometimes a lack of interest in sex has a physiological cause, but sometimes it's just a matter of personality. Unfortunately people don't talk about it much because the media and society in general tells you you're unusual if you're not constantly on the prowl. But you're not alone. Is there another counselor you could talk to about your troubles?
