I agree in supporting the addict in recovery as long as they are actually working recovery. It's pretty easy to tell when they are and when they are not. If they are not willing to work, we cannot make them. Nor is it healthy to lose yourself or drive yourself to a nervous breakdown while you tolerate their using. Let's not even talk about the affects on the children.
As many of us have said, addiction is so selfish. If it's a team approach, one must look at the affects on the other members of the household. Many times the most healthy approach is to not expose yourself or your children to the addict behavior.
