An older boy and I like each other

Hi, my name is Simone and I'm a 15 year old freshman. I have been talking to this one boy in my friend group more and more recently, and I think he likes me. He's very kind and polite, and we have a lot in common. The problem is, he is a senior. The age gap to me is very strange even though I like him. The thing is, he isn't just trying to get in my pants, I think he just generally likes me as a person. I know a lot of girls say this about older boys, but he really is different. I'm keeping in mind the age gap as I move forward, but it's something that might be hard with my parents. I don't really know what to do at this point. Any advice would be helpful.
