Whatever program she chooses is up to her. After three inpatients she has all the tools in her toolbelt -- whether or not she uses them is her choice. Your judgements about her choices are irrelevant. The only relevance is whether or not she stays sober from this day forward. So... what will you do if she doesn't?
The bottom line is that this is the time for you to figure out what YOU want out of life (like serenity!?) and to take steps to make that happen. As you know, the only thing you can control is YOU.
We'll be thinking of you. Good luck and keep us posted. (((Hugs)))
