Thanks. My wife goes. I don't see the value in it, but she gets some insight from it.
One of the insights she said she gained is that my feelings are often validated by the group. She didn't want to throw our child out of our home, but heard a few stories about how parents turning their back is what really helped the addict, because they were no longer being enabled. So she came home and said "you were right." And that's another valuable part of this story. In order to turn my back on my best friend and throw her out of my house, I've needed to become angry. It's a coping mechanism, to keep me from feeling destroyed and help prevent me from being manipulated.
But I'm afraid. She's my first child, so beautiful, a straight A student. And I miss her, so much...
Now you've got me crying about it.
