I am sure you are comforted by the knowledge that your children will be with a sober parent(s). They deserve that, and bravo to you for standing up for them. So many kids go to AM's just because they are the "mother". Kids should never be with an alcoholic. Thankfully, my kids are old enough to say where they want to be, and its just happens that they have picked the sober parent (me).
I can't begin to imagine what you have been through with her, we all have different situations, but my prayers are with you and your babies.
And with your wife. If she can do this , you all win.H
