Hugs....Z. Big hugs. You are doing the best thing for you! You mention his sister-I'm sure there are others. Remember addiction requires enablers and it sounds like he has plenty. You ask why he is the way he is-I second what dandy said about reading Garrett's articles-they are totally spot on and accurate. He is all the ways you describe bc he is an addict. I'm sorry you are hurting. Do know you will have peace-true peace!!
