Thank you very much for that response, I really appreciate it.
You are right-on when you correct me about how I said my step-dad's behavior "drives" my mom to drink. I misspoke.
From your response it sounds as if you feel that an intervention might be our best hope. I will be in contact with the rehab centers and do some investigation with them to see if that is indeed the best course of action.
We have tried everything else up to this point...I do not have much to lose.
