How do I get him to like me?

Okay so I like this guy and have liked him for a while now. We text sometimes and see eachother on the weekend but we rarely talk. He is a năm older than me and goes to a different school. Most of the guys at my school say that I'm pretty but im short...does that have to do with anything? Can any of bạn guys help me bởi telling me what to do for him to like me? If bạn need anymore details just ask and I'll answer. Thanks alot :)
