Something I forgot in my post -- don't forget perceptions. You perceive that you were there for your W emotionally. She obviously feels otherwise -- or at least she is concentrating on the times when you weren't and can't remember the times when you were.
Of course you weren't such an S.O.B. to your wife. It's her mindset. Please try to understand that. I was in her place. Your W got to a place where it didn't matter what you did, everything was wrong, everything had an alterior motive (if my spelling is off, please excuse me. It's cocktail time!).
Does this sound familiar -- you'd try to hug her and she'd pull away, afraid that it would lead to something else? Did she not want to kiss you anymore? Did she not even want to hold your hand? If so, she was thinking you only wanted one thing, and it wasn't emotional intimacy.
It sounds like you guys are on the same team now, walking the same path. It'll come back. Believe me, it will.
