Thus guy keeps hanging around and getting inappropriate because you leave him a big opening to do so. Stop telling him that you need a break and aren't sure about this and that. That's a bunch of stalling around. This man has zero interest in being "your friend." He is pursuing you for sex. That's what he wants. He's probably in contact with other women in hopes of a sexual hookup. If your answer is no to the sex, then say that. You have never been on a date with this man, and he's probably not ever going to invite you on a real date. He's creepy, whuch you know yourself. Stop heming and hawing, which encourages him to hang around.

Get up from the keyboard and go out into real life. What you need is out there.
