Yeah the restraining order is looking real nice right now. The person in question is showing up in my driveway every couple of days being crazy, attempting to throw cops and lawyers at me for laws that don't exist and other absolutely insane things. They have also attempted to assault my mother, but I stopped them. I'm on less than "Friend" status with this person. I know just enough about them to know who they are. It's a real weird thing, and I'm considering feeding them to my 100 pound guard dog if they keep this insanity up. (That's a joke, don't go nuts)
Call the cops.
This person sounds dangerous and you should get a restraining order. Like, today.
Best of luck.
