Wow... quite the tale... I have not had that much experience with this sort of mental illness stuff like a professional would, which is my first though: see a professional, someone who has dedicated their life to helping people with illnesses like this one, so you can be sure you are doing the best thing in the best way; don't leave it up to your intuitions here... you want to know form people who have studied this sort of thing what to do. So see one, even if just to talk.

I must say, I was really touched by your story. I want to say how impressed I was with your kindness and loyalty. You really are a good friend. However, there are lines in anyone's life that must be drawn. A person, no matter what they were under or dealing with or any other excuses you can justify, who says they want to hurt you in any way, let alone kill you and your family, is beyond your power to help. Period. I know, I have been with people like this (not quite as extreme) and you feel the exact opposite when you're in the situation, but please, get help. From a professional; you are in waaaaay over your head, and you can only make things worse unfortunately. I'm glad you have come to the decision to call off any type of serious relaitonship... but think about what has happened with this person... sorry to bring up sore events, but he stole your virginity in your sleep for crying out loud... You are being blinded by so many things that you cannot see the obvious danger and risk you are putting yourself in. You say you feel bad becuase he doesn't have any friends... well, have your moment of pity... ... ... there. Now get over it. By sheilding him from the real world, you are hurting him far more than you ever could with honesty. Please just be true to yourself and dont back down, for BOTH your sakes. You say you dont think he can handle a blow like that, well, honey, there are much worse things in the world than having a girl just want to be friends. Stop being this man's overprotective nanny and live YOUR life; I know you are concerned for his well being, which is very admirable of you, so maybe you will want to get him help. Sex and videogames (fun as they both can be) is not life, and you are being treated like shit. For your sake, please I beg you to seek safety. Mental illnesses like this are nothing to toy with or hide under the rug because you think you can deal with them yourself later. He needs to be in the real world, and by trying to protect him, you are hurting him by keeping him from reality. I don't mean to rant on like a doctor, so go see a doctor and have him rant for you! My biggest concern is for YOU, that you are safe; no matter how "changed" or improved you think he is, he has hurt you and threatened to kill you in the past. This is serious. Get help. And don't put it off; find something NOW, right after reading this post, I would strongly recommend. You do want to help him, right? Hard as it is to swallow (I know) this is the best and really only thing you can do. You have not studied this for x number of years... there are people who have and deal with this kind of thing every day. THEY can help BOTH of you... don't try to save the world... what good is that if you can't live in it? Please find a doctor of some kind right now and go form there. Also please let us know how things go; I for one am quite concerned and worried... Best of luck to you.
