Is he a friend or does he like me more?

Okay, so, there is this guy in my grade at school. We have been friends for a long time, since third grade. well, we are now in eighth grade. we talk all of the time and hang out a lot. we always have so much fun together. he says he only likes me as a friend but I think he likes me more than that. we are both in FFA and we both are on the same float committee. we stayed after school to work on stuff. when I finished working on laminating stuff, I went out into the shop. we were watching a couple of other kids paint. we talked awhile. then, when those to left, we were the only ones there. it was the first time we were ever alone together. we talked more. he kept trying to make me laugh, and succeeded. he made a bow out of wood and string and used little pieces of wood as arrows and kept flirting with me. as far as I know he still has a girlfriend, but that might be over. I don't get into relationship status with him. anytime we are on a bus going somewhere, he says something random that has to do with the two of us. most of the time, I don't understand. I have asked my friends about it, and they say yes. any opinions? or signs to check for when I see him? it would be greatly appreciated.
