Thanks so much for your response. I am going tomorrow to see if I can find the book.
We did try something different last night that seemed to help. No sex, just some physical contact. It was nice, and even though it didn't lead to anything else, it was nice just to be held and feel loved. Like I said, I think that part is just as bad as not having sex.
I see now that I'm not alone. There are many others having the same problem I am who don't want to call it quits. Thanks to all of you for sharing.
