I would immediately call the police and get a restraining order on this person. Things will only get worse, as long as you feel the way you do, he wins. Don't let him win! I spent 6 years letting mine win! take legal action and get rid of this bastard asap, he is trash, god will judge him, until then he should not have the right to be anywhere near you. You are no it, that is him talking to himself out loud, he is calling himself IT, that is what is called projection. People say to you what they think about themselves, you are none of the things he says about you. To him, you do not exist as a person because he is a sociopath, he is trying to dehumanize you, that is what sociopaths do, but the fact is, his brain doesn't function right, literally, his wiring is all messed up, and all you can do it protect yourself with the law.
