Txhelp,
That is exactly what I am hoping for - that in a few days the anger will subside and he will have some real emotions. He is not thinking clearly right now. A friend of mine and recovering heroin addict told me that in his mind, he has already relapsed even though he hasn't actually abused drugs. He has been thinking about it, he still wants to do it, and he is angry at himself for feeling that way. He is angry at himself, not me, but he has no one else to take that anger out on so I become the "punching bag". I get it, and I try not to take it personally, but some things hurt no matter how big of a wall I have up.
But I am going to try my best tonight to not take what he says personally, and just be supportive. I think it will get a bit easier as each day passes.
