I'd say he's an F-31.9, severe with psychotic features. The best you can do is stay away; or if you actually have true love for him seek counseling. I could tell that you're here for him, and well, he's a pretty bad case but nothing to worry about too much that a good therapist and a psychiatrist (and again, counseling at first with both of you participating so you can convince him to treat himself). If he refuses treatment, then you'd do best to take a long break from him and see how things would develop in the future.
