Does he like me or is personality naturally nice..

When I was 11 I met a boy he was in the same class as me at first I didn’t think much of it but he started always coming up to me and asking questions like where I’m from what hobbies do I have, so I sorta became friends with him but it was more like he would tease me all the time . Then we went on a class trip that’s when I realized I fell for him I started to notice how I’m always slightly watching him or trying to get closer and back then I thought to myself what ew no I’m 11 I shouldn’t be thinking about this stuff but he would always come up to or ask if I wanted to race down the hill with him this weird friendship of him teasing me and hanging out with me kind of decreased after a year mostly because I was trying to avoid him since a girl in our class confessed to him but also because I wanted to focus on school anyway there’s this one time where he did something that stung like a bee we were choosing soccer ball teams it was mostly boys and like two other girls one of them being the girl who had confessed to him and he was one of the captains who was picking team members and everytime we played soccer he would choose me but this time he looked at me mouthed sorry and choose her it’s not even a big deal but why, why did he have to mouth sorry two more years went by and we were 14 nothing to exciting happend in the past years but him constantly teasing me but I coldly ignored him to the point where people thought I hated him but that wasn’t the truth I was just trying to convince myself I did so now one more year by and I’ve finally gotten over him but just my luck I sit next to him in class he always being difficult and confusing to the point I don’t if he likes me or if he‘s just teasing again but I genuinely like talking to him there’s this one boy who sits behind us and he asked if there’s something going on between us we both faced each other and gave he me a smirk and the said to the boy who sits behind us no laughing then I said yeah I’m like this with everyone we’re just friends. Honestly I’m confused I don’t want to go back to those times wondering if he likes and staying up all thinking about that
