Does my guy friend like me?

Okay so my guy friend and I have this weird relationship. Sometimes he will grab me and push me back onto the wall but he does nothing. Then he started biting me, recently he started to bite me on my neck which is strange. then recently he grabbed me threw me on the bed and was coming close to my neck to bite me and stopped and walked away. I don't know what his problem is and when I mention I like other guys for advice he never says anything just kind of ignores the ques.
