Confession: I Don't Like Him, But He Won't Leave. I Even Cheated

I'm with somebody that I'm not happy with, I've tried many things like asking him to leave me alone & even cheating but he still won't leave me but he also got aggressive once when I told him.

I wish he would die since he didn't want to leave me so now I just cheat in hope of finding someone who will scare him away from me.
