If I was upset or cried my husband would cry with me. Before the coke took hold. There is no love towards me he feels like a different person. Like you say if his dad died he would have no emotion now.
I have stopped getting angry with him and try to be what was my normal self its hard work when all I want to do is rip his head off. Hopefully he will realise that coke is the problem. It has definitely altered his mind.
