Is he my boyfriend ?

So theirs this guy that I’ve been talking to and we’ve had history before but I wanted to try it again and I feel like I’m forcing it. He tells me he doesn’t want me and he’s said many mean things but I continue to chase after him and I can’t understand why!! He’s told me he loves and cared about me then a week later says that he wants nothing to do with me. I honestly feel like I’m doing something wrong. I wanna be happy...I wanna be happy with him. I’d do anything for him but he doesn’t believe me..I juts don’t know if I should stop or continue trying.

He’s leaving soo anyway to go back to school

Which he’s even asked me to come with but idk what to do I just need some advice if anyone can give me some?
