Ever think of getting a survelance system? Tape everything he does... grab a camcorder whenever he's banging on the door. Document everything he does and says with dates and times. Unfortunitly it sounds like your state doesn't have stalking laws.

What I'm wondering now... if he came into your house and "he hurt me in more ways than one that night" why didn't you go to the police then? I mean hindsight is always 20/20, but if someone physically harms you in ANY way they need to know... then they can build up a file. You need to get some good, solid proof of what he is doing because he is a real danger. And the advice of getting your neighbors involved sounds good. SOMEONE must know what is going on and see it or hear it.

Get a restraining order as well... that way if he violates it he is commiting a crime and can be prosecuted.

Best of luck, hon, I hope you can get rid of this guy. You shouldn't have to change your life because of him and you shouldn't have to live in fear over him.
