Stay safe.....do not hesitate to get a protective order if he threatens you. When people" use" they are insane.....sometimes in a blackout.....Call the cops if he is verbally abusive or if he throws things....that is viloence. You deserve to be safe. He needs professional help. I personally hope he stays locked up until there is a group home or some treatment available to him. He is sick. He will take his problems out on you. Been there, done that, have the t-shirt in 5 colors......He does not have the right to be there if he is taking your pills, not paying rent, being abusive. He is bound to qualify for special group home treatment if he has mental problems. It will not get better. STAY SAFE! Do not engage in conversation with him if he is using. Get out of his way. Go somewhere safe.
