Right now he is not sure where he stands, so how is he going to tell you? But keep in mind that he is still living with you. So long as you don't add fuel to those doubts, they will extinguish themselves.

I still don't understand why he lost all his affection for me, and as he said in c , he wasn't sure either.
At the right oppurtunity, such as an quiet moment when you are snuggled next to him, try posing a question like, "When you think of us as happily married, what would I be like?" and just listen. Don't respond to anything he states other than to validate that you heard what he said. Just absorb it and thank him for being open. Then ponder what he said in your mind over the next couple of days and try not to criticize it. Somewhere in what he says will be how he would like to feel about you. From this you should be able to make some goals that will bring you closer together and come up with some 180's to strive for those goals.
