Are we combatible with eachother?

I'm 15 and a cancer but I'm a shy type and I like this one guy who is 16 and a Capricorn and he's a pretty shy and quiet person. I get this feeling that he likes me because he looks in my direction a lot, sometimes smiles, follows me sometimes especially during pe (well when we go to a different gym), he's sometimes red, one time he held the door for my friends and I and he crashed into me while I was walking through, and well we said hi and smiled to eachother and then he started acting more strangely like waiting for me by the door when I don't know or moves next to my badminton court and walks around a lot and it seems like he waits or looks for me lol not so sure and a few girls like him and asked him out but he said no. And one time we had a drill and he's in the front of the line and I'm in the back and a few minutes later when we were about to go to lunch I turn around and he's standing behind me talking to his friends he does that at times well the appearing around me and before when I got close to him he would start moving around a lot and keep looking at me and try to run away haha. Plus he's good at eerything and is very smart. Anyway do you think we are compatible and does he like me?
