What Do I Do about this Guy?

I’m in the band, and I’m a sophmore. This new Freshman guy just joined this summer and we starting flirting. Not in the serious way, but the elementry way. Anyways, we just recently went to band camp, and on the bus, he asked me to sit with him, but in a joking way. On the way we stopped at a Wal Mart to eat at McDonalds and we walked and talked together through the store. I jokingly asked him to buy me this plastic 88 cent necklace and he did. I thought it was sweet. Well the boys and girls were seperated at camp and only got to see each other during pratice or meals. He barely talked to me, but everytime I turned around he was always staring at me. On one of the last days he was all over my friend, Jane, flirting with her the REAL way. Well this other guy from another school named Chris kept trying to hit on me and stuff, I didn’t like him but I talked to him sometimes and Anthony (that’s his name) was always looking at us like he was jealous. One time Chris touched the necklace Anthony got me and asked me about it and Anthony was all “I got it for her, you know”. One time, I tried to make conversation and he was completely rude and standoffish for some reason. On the last day, we had a dance and he was dancing with Jane like the whole time. But then everytime I looked at him, he was staring at me again. On the bus ride home, there were no other seats, so I sat with him. Throughout the whole trip, he completely ignored me and talked to the two girls sitting in the seats beside us. We stopped at Wal-Mart/McDonalds again, and he walked with them, while lonely old me was left alone looking at the new Harry Potter book. So okay, I’m completely just pissed that he’s ignoring me when we finally get to back home. Everyone’s rides slowly start coming and it’s just me, him, and like three other people and our band director. My mom finally comes and I load my bags in, and get in my car. I turn around as we’re driving away, and he gives me this look. An undescribable look. It made me completely forget that he was an ass to me on the bus. So now, as I sit here, I don’t know what to do. There will be other boys this year, but I want to hold on to this one. Even though he sends me mixed signals, I still kind of like him. I don’t want to deal with the whole “Does he like me or her? drama this year, but I don’t know if I should just let it go. What do I do?
