I would like to know...

Hey, in almost 14 and in high school. There's this guy that I really like. He knows I like him because my friend accidentally told him once when trying to hook us up. We both talk to reach other on Snapchat through all hours of the night sometimes, but if it's later then 12:30, he will tell me to go to sleep and make sure that I am. We flirt with each other a lot, and mess around in class. We hug each other when leaving. He has told me that he'll always be my shoulder to cry on and made me promise to always go to him if something is bothering me or i feel like crying. When I had injured myself and was on crutches, he had offered to carry me to class. Are we just friends? Or do you think we might be becoming something more? Any advice?
