He’s not going to know if he likes you more than the other girl if he doesn’t really know you and doesn’t have a chance to talk with you.
I think you should be friendly and chat with him. Let him see you’re easy to talk with. That’s not the same thing as throwing yourself at him. Just be nice and friendly, not flirty. You want the guy to respect you.
I’m sure you like him a lot, but it is way too early to be talking about ‘love.’ Love is far more complicated than just liking a boy in your class, so don’t make a bigger fuss than it needs to be. Talk with him, and you might find he’s not actually as wonderful as you think he is.
But you should always spend time with someone and get to know them properly before deciding whether or not you love them.
