Leznew, is having her home something you want or something she wants?
I ask because the recommendation to stay in a halfway house is a good one that will help her stabilize in the "real" world while surrounded by support.
They say that the real recovery begins after you leave rehab, this is when you get to test your tools/coping skills. My prayers go out for you and her that she does whatever she needs to do to stay well.
