Yeah, rehab. She's going through a lot of changes now and becoming more self aware about her life, and so you have to expect these new behaviors from your wife. Be careful of guys trying to get into her pants too, it's so common in rehab situations. It's people going through changes, feeling like they're living again and experiencing different people and finally feeling like a connection to life is being made - which, prior to rehab, was not there. I've been there my friend. Many, many changes. Good on you for wanting to understand, as well.
