YOu need to let him go and get a hold of yourself. It is still all new and far from over, IMO.
Do not dwell on him so much, let him be, do not question why he does/says this/that, etc.
You don't have to take his calls every time either. Let him wonder if he is so concerned.
Just let it go and let him be and you will feel better in the long run regardless of how this will end up.
