A good way to detach is to take the addict out of the picture. Tell him he has to find a different living arrangement. It is so difficult to live with an addict whether they are clean or not. Having to walk on eggshells afraid of the next temper tantrum is no way to live. You have a child in an adult's body, but unlike the child, the adult can do a lot more damage. My daughter can never live with me again, clean or not. That is my boundary. I will no longer put up with the moodiness, selfishness and the verbal abuse. Sending some hugs and prayers. Marle
