****when he went to bed he made a point of coming to me and giving me a hug goodnight

That's great!

I assume that any contact with you physically will remind him of the guilt that he is already burdened with. That is not to say he does not want to be intimate; it's just flooded with emotions...bad ones.

Keep on puggin StrongBear. Your marriage is where it is now because of YOU! Be proud!!!
