Then there is nothing else you can do. We each must take responsibility for ourselves and our own actions. Don't allow yourself to become his hostile outlet. Work on healing yourself from 5 years of the emotional roller coaster that mental illness brings. At this point, he must find his own way even if you know it isn't the best path. He gets to make his own choices even if they are wrong. You must take care of yourself. I am the adult daughter of a mentally ill father who abused me emotionally for years. It is extremely hard to let go, watch him fail miserably but I can only take care of myself. Mental illness causes some to use and abuse those close to them. It is time for you to move out of his destructive path. Sometimes they must hit bottom to ever look up and work towards getting well. My heart breaks for you but he doesn't definite your life. You do!!
