I think that leaving a drunk is the best thing for all concerned. They cause way too much damage and cannot be successfully DB'ed anyway.
Detaching helps unless you live in the same home and they hve responsabilities.
If they get as bad as Pass' husband is you need to show them the door... she came home today to a pile of dog poo in her house... you think detaching is going to help that?
If you take away his responsaiblities he will jsut give you a big thank you kiss and get worse...
You tell him to shape up, or get out.. THAT is AA 101
INGORING the damage isn't going to make it go away.. Pass has to LIVE there TOO and so do these kids.
