Welcome to SR and HOORAY for you for taking care of you and your children! I sent XAH to the curb back and July and even though I had doubts now and then, I know I did the right thing.
I actually think that rehab is the perfect place for someone to get bad news (of course, I haven't been on that particular side of the sign-in sheet myself, but I would think). There she lives and breathes a program that can help her deal with that news before she is released.
Best of luck to you on this leg of your journey. Good to have you here.
