How would you call that ?.

It's been like a year and a half since I broke up with my ex boyfriend, and I never was with anybody, not a single boy until three weeks ago. So there's this guy, that I keep thinking about. We go to the same college, but not to the same classes. He's really something. He has this great personality, he's really nice and talkative with everybody, and he's always laughing and making jokes. Every time I see him we laughed a lot, he's always making me laugh and that's something I really like about him. I'm not sure if we have a lot of things in common or not, because it's been like three weeks since I know him, but so far I like what I know. I really enjoy the time we spent together, and when the time is up I think ''I wish to have more time to spend with you'' and since the break up no one could made me think like that but him. He's like a mix of boys but in a boy. He studies, he's responsible, funny, enjoys to spend time with his friends and go out and have fun, is someone you can talk to, and he plays in a band. I don't know what band is, never listen to it, but the thought of that makes me think like he's a bad boy or rebel boy and I have like a weakness for those kind of boys. But it's not that either what leaves me thinking about him. He has something that I still couldn't figure it out and that's what leaves me thinking. He has this ability, this kind of mystery that I really like. I don't think he likes me because I'm not his type, I think he likes a different kind of girl, more like him, more heavy metal type. But I can't avoid this feeling, I can't help wanting to see him and spend time with him. There were a couple of times when we get a little bit close and I had to watch to the other way because I couldn't help wanting to kiss him and it's not the first time. There are times when I see him right to his eyes and I think ''I just want to kiss you'', when he touches me or hugs me I feel like doing the same but I'm too shy I think, so I just see his eyes and laugh. So how should I call this ?. It's not love but it's not a passenger thing either. I think I'll go with the flow and see where it leads me.
