What should I do about this?

I've been constantly texting one of my guy friends daily for a while now and we get into conversations about everything and its just amazing how easy it is for me to talk to him. I feel like I have no one to talk to about him because even my best friends wouldn't understand. I go out with him and my group of friends all the time so it's not like I don't already go out with him. We spend a decent amount of time together, except that we live in different towns so he goes to another high school. But I'm always thinking about him and we always talk but I don't know if I like him, And if I do I don't want to admit that I do. I'm a senior in high school so I feel that I'm old enough to be able to tell him how I feel but I don't even know how I feel...I think I like him or maybe I just like talking to him. I'm not really sure lol my feelings are very intertwined and mingled right now, but what should I do? Thanks!
