Hi Virgo.
I realize the intervention is for him, not her. My point was rather that interventions that don't succeed can be devastating for the loved ones that try to stage them, and it's interesting that no one intervenes to stop the interventions (or other self destructive codie behavior) sometimes.
I'm glad you're already attending alanon. I hope your daughter gets a lot of meetings under her belt before she participates in this, if she's bound and determined. And IF she's bound and determined, all you can do is let go... just like with an alcoholic.
Hugs!
