There's a section here called Friends and Families of Substance Abusers. I've seen a lot of great input there. This will be a difficult period for her, but she doesn't have the right to start taking it out on you. Unfortunately if someone doesn't want to open their eyes to reality they're not going to. A lot of people would be feeling remorseful during this time, and waking up to how their addiction helped create their problems, without blaming others. Hopefully that will happen for her, too.
