This demonstration of bizarre assaultive behavior, not just thinking, but as you report is an actual attack. You may be emotionally attached, but you have been given numerous warnings that this is a dangerous individual. The likelihood is that if you continue this relation a time will come when his aggression is directed toward you. I would strongly urge that you carefully break it off before you are physically assaulted. Again if you break it off as I suggest be careful how you do it so you do not set him off against you.
Best wishes and good luck
