Do you think he likes me even though he does not admit it? Please read details?

I have homeroom and 7th period with this boy named cody. He has a gf and he does flirt with every girl he talks to I would say. He flirts with me everyday. The way we flirt is like elementry school but Im a junior and he is a senior. He will take my book bag off my desk or try hitting me but not hard enough to hurt me. He starts it everyday. I dont have to look at him in order for him to start flirting with me. What is your opinion on this whole situation
