I think my husband wants to leave, advice?

Hi all. Please keep in mind we are believers, and marriage is very important to us. My husband and I have had issues in the bedroom, of my own fault I can concede. I am not unattracted or unaroused by my husband, but I do have a strong hatred of myself that prevents me from being open to sex. It has caused my husband great pain, and he has made this clear to me. I try to fix things and then get discouraged and just hope things will come together magically. However this is not the case. It came to a head and we have taken a break. I want more than anything to put aside my fear of failing and give this an actual, solid shot. However I don’t know how my husband feels about this. I am afraid that he is already trying to move on. Please be gentle. Divorce is not something we take lightly. We are an amazing pair besides this situation. I’m tired of holding myself back, and want to make things better.
