When someone is trying to recover cold turkey right now, while waiting for a program, it's been a week since he last used drugs and alcohol. What kind of behavior will he have? He says that I let him use. But that's not true. Now he wants to be away from me. Is this normal behavior? If so what else can I aspect from him?

Irrational behavior is normal. Lashing out is normal, looking for someone else to blame is all very normal. Addicts going into recovery will struggle with mood swings all day long and they will try to pin those moods swings on other people. In truth it isn't the other people that are acting differently, it is the addict that is changing.

Be verbally supportive and be sensitive to when he needs space. Make boundaries that you both agree on to help keep the recovery on the right track.

He was most likely using when you both met... now he is sober and is seeing you for the first time. Don't try and fix that. Let it go... hard answer.. I know.

Erratic behavior and accusing everything under the sun is normal recovery behavior. He's not used to reality and this is quite apparent by what you have described. Just remember, his brain has been lulled for years by drugs (and probably a few billion brain cells killed in the meantime) so don't expect a very rational human being for quite sometime. Try to relate to you being on an all night drinking binge and trying to be coherent the next day. It's pretty close to that sort of mind fog that he's having right now. The less argumentative you are the better. He probably doesn't remember much either from one day to the next right now either.
