Am I in love with him!? Is this actually real or do you think he doesn't even love me?

Sorry this is kinda long guys. I'm dating a guy and we've been dating for four months. I'm a little weird and the outcast of school. I try to be different so I can be an individual and not a robot like everyone else in school. The guy I'm dating is a really popular jock and everyone hates that we're together. He says I'm just a little left of center and that I'm a little out of tune. Some of the other jocks say I'm paranormal. Who wants to be ordinary in a crazy, mixed-up world? I don't care what anybody says about me anymore as long as I'm his girl and I'm with him. I've always been my own person and odd, but I always let peoples opinions get to me. He is on my side and everyone else (everyone in my highschool) they just roll their eyes. He gets me because nobody understands. It's like he comes and take the chance. He said he likes to look inside my wild mind never knowing what he'll find and still he wants to be with me all the time. He says I'm the one to see the sunshine in the pouring rain. Most people in my school think I'm crazy but he says it's okay. He says he has seen my secret garden where all of my flowers grow, because I once told him that was my favorite book when I was little. He says in my imagination anything goes and it is all amazing to hear which is strange because everyone including my family doesnt like my imaginative side. He says I am all he wants and everyone else just reads me wrong. He comes and holds my hand in front of everyone. He said when none of the pieces fit I make sense of it and still I want him all the time. Do you think I am in love? And do you think he is in love or he's doing this as a joke? I trust him, but my best friend doesn't trust him. I am 16 he is 17
