Well, first off, hate is a very strong word. If you don't like him, a better approach would be just talk to him and be honest in a nice way. Tell him you mean no offense, but you just don't like him and wish that he would leave you alone.
I hate this guy, he likes me. I ignored him all day and i think he got it. He called me ( i didn't realise) then he was like, to think I lked you. I dont want haters. Any advice?
