I'm sorry, but it's not at all unusual. It is quite common when the addict decides to enter recovery that they want to distance themselves from everyone and everything that reminds them of their past. At this point, she is very confused and isn't sure what she really wants, but she is right that she isn't relationship material right now. Her main focus should be on her recovery. You may be right that her mother's place isn't the best place for her to be after rehab. The best place would be a sober living facility where she can transition herself back into life.
