BOYS: Do you think he likes me?

Okay, so here's the story. I like this guy named Nate. He's 14 and I'm 13. I met him through my sister, who evidently was trying to set us up on a blind date for a while because she thought we would like each other. Anyway, he doesn't talk much, he's really shy. He won't even talk to his dad. Back to the point, he came over for a camp out and we were sitting next to each other by the fire. He kept looking over at me and asking me if I wanted him to move out of the chair so I didn't have to sit on the ground. At like 3 am, we kept singing a song back and forth between our tents (they were facing each other, like 1000 ft away). In the morning, there was a wolf spider in the girls' tent. When we told the boys, Nate's eyes snapped open and he grabbed an air soft gun and shot it! Another time, we had a party and decided to go night swimming. I got out because I had to go to the bathroom and my brother tried to push me back in (he's 14). I thought I was gonna get pushed back in (bcuz he's stronger than me), but Nate grabbed him off me and tried to push him in. I had time to run by, but Nate got thrown back into the pool. Whenever I see him, he doesn't talk to me much, but he looks at me out of the corner of his eye and looks at me after he tells a joke (usually nervously laughing). So does he like me? Serious answers, please.
