My bf never asked and we didn't talk about it unless I brought it up. Even then he didn't offer too much of his opinion on things. I think as long as he knew I was getting help, he was happy. I was excited about my recovery from the beginning so I had no issue with sharing info - not every A is going to be like that though, I don't think. I am also the type of person who if he would have been breathing down my neck about it and asking many questions, I would have gotten defensive as if he were accusing me of lying.
You know what he's like not in recovery, you will be able to tell when he is in full swing trying to recover 100%. I say tread lightly with questioning...this is just coming from the other side of the coin. I know people want to know what's going on, but just like your emotions of dealing with him, a recovering addict goes through a roller coaster of emotions too.
