By the sounds of it, you are quite young (or else not a native English language speaker) and so I imagine you don't have much experience with relationships. I would say that it is important to distinguish between a crush (which is what it seems you have) or being in love. I would suggest to be in love with someone you'd have to have known them a long time and be close to them often. It's fine to have a crush on someone but that doesn't necessarily mean a relationship between the two of you would work out. I have had crushes on people that I would not actually want to go out with, so it is important to understand what you want from this person and how close you are. Hope this is helpful~
