I know the answer that makes most sense ... that answer would be yes! walk away! Run! .. but I also know it isn't that simple. After the 9 years of A.A and rehab you mentioned.. I can't say there is no hope ... some people against all odds turn their lives around .. but do you want to spend your time waiting for a miracle?
Really going to be up to you and how much more you can tolerate.. wish I had a better response for you.
