I don't know how wise I am...but I know I have been through my share of relationships that suck, and I am sorry you have to go through this! There are literally thousands of reasons he could be acting this way, from some sort of disorder to...anything. I agree with Capp, as I say in many of my replies, communication is everything. If you can have a calm converstaion and state your feelings, hopefully he will do the same, let him know how important communication is to you, and you need to talk through this. If he can't, or won't, therein lies a problem I have no answer for...except maybe it's time to move on. You don't deserve to be treated like this, and you don't have to stand for it. You are a worthwhile person and your needs need to be met as well as his.

GL and God Bless!
