He is really irresponsible. Call his parents next time or the hospital and say that he is endangering your life.

That sounds more like explosive personality disorder, I'd call the cops and tell them they need to take him to a psychiatrist to be under watch until they find a way to balance his hormones although it doesn't sound likely.

Good thing you called the police and had them file a report, right OP?

If you're still there you're crazier than he is. You should call the police as this behavior needs to be noted on his record.

it's time for a restraining order OP let him find a new room mate!

MOVE OUT !..while you still can!
