don't put yourself under all this stress, you have done absolutely nothing wrong. From the perspective of a recovering alcoholic i think your husband is going through some massive emotional and physical changes so you need to be patient for a while with him. I would definitely suggest you to read the chapter of the big book dedicated to the family afterwards. Lots of good advice in here too. Be patient but don't put the issue off for too long, you have your needs after all too, so do approach him about it.
If you have feelings of resentments towards him, maybe try going to an al anon meeting?
Best of luck x
