MSM, I fear this is happening to me too. After nearly 2 years of rejection and frustration, I think something has broken down inside me. I too have been having these passionate dreams, but when I awake, they mean nothing and are quickly forgotten.
I always figured that prolonged exposure to sexual abuse (which is exactly what LD spouses are doing to their HD spouses) would result in some sort of negative effect. Now I know, it really does.
I am very sad to see my drive slipping away. In fact, I hate it. Nevertheless, it seems to be happening.
I feel now that most of my future energy will be directed, not toward repairing my sex life, but toward not resenting my wife for killing something that was once so important to me.
