You can still love your son, but do it from a distance. At 24, it is time for him to make his own way in the world. I know it is hard, but do you still want to be doing this 10 or 20 years from now. Take care of you and the relationship that you have with your partner and other sons. You are not helping your AS by giving him a nice place to live, food in his stomach and a soft place to fall when he is using. Hugs, Marle
