can a guy explain please

If anyone can help please do. Id appreciate it so much. So there's this boy that i really like. im a freshman and hes a sophomore. We're both in band and talk a good amount. We know the is usual stuff and a little private stuff about each other. Today we had a competition and we were sitting in the bleachers together for like two hours. He kept offering to buy me something to drink or eat and i thought it was just him being nice which it probably was i kept saying no thanks but he bought me a something to drink anyway and he was like concerned cause he thought i was going to get sick . We were picking up trash and i asked to take his, and he said no and i insisted so i put my hand out and he would not touch me he just hovered his hand there and i just grabbed the trash. I heard if a boy likes you he'll kinda go outta his way to touch you.i duno i really want him to like me and it may sound weird but I dont wanna get stuck in the friend zone but im slipping in there. whenever a convo would die he'd try and keep talking and he like would not stop smiling when we were in the bleachers. And he smiles rea rea big whenever i say hi or poke him. So yeah thats the end of that i like him a lot im kinda afraid he wont like me:/ so im confused how can i get him to like me?
