Bond - I have read up on alcoholism and depression, and the traits match. But...I don't think she's totally out of control. She's definitely cut way back while her parents have been here. I don't think they'd be very helpful in an intervention scenario. W would deny it and they'd take her side.
I see your point with the ultimatum - but I don't want to be the one that leaves, and I don't think I can "kick her out" - how else could I make it work?
