Another thought I had...if your W had that much of a low self-image to begin with, she may now be thinking "Why would GH want me sexually knowing what I've done?"
I, too, have difficulties accepting compliments. Just like your W, if someone says "Gee, your hair looks nice today." I answer with "Thanks, but I really need a haircut." Although on the inside....I was secretly very appreciative of the compliment.....maybe that's my own personal issue - it's not as if I don't feel that I deserve the compliment, rather I'm just not so very good at accepting it because I don't really care what anyone thinks of my hair. Perhaps because that's not my LL?
Sorry if this doesn't have anything to do with anything. LOL
