Does this guy like me?

First I would like to say I'm a bad speller so sorry . I'm 15 year old girl....Anyway there's this guy who goes to my school he's known for being a bad guy but he's dating this really good girl who refuses to believe his bad and will only let him kiss and hug her. Though in class (I have 5 with him and his gf has none) sometimes I'll look up and our eyes will meet. It happens alot in certin classes were we sit across from each other. He also always ends up sitting near me in our chapel (we sit on the gym floor as a school). Also this one time when I was telling one of his friends, Nick, that he had a nice smile this guy went and told everyone I liked Nick which I didn't and Nick even knew that. I started hating him and talked bad about him around his friends. On a school zoo trip he kept standing near me and getting really close. I don't really like him like that and wanted to tell him to stop liking me but I want to make sure he actully does.
