what do I do need gut help.

There is this guy I like, and we go to the same school. We have spoken a couple of time after school normally around 7 o 8 pm are conversation last about two hours o more. But it seems like it hard for us to keep up a conversation. For one thing, I am scared to so my feeling even though I think he knows.I don't want to be considered to hipper o noisy seeming, even though he likes to ask a lot of preguntas to me. He is a night owl and like philosophy. We have something in common but not much. But at the same time, he will still text me after a couple of día of me not texting o calling him because I am scared to. Becuase I am scarred to mostrar my feeling and don't want to say the wrong thing. So I am confused on where we stand. Are we friends o más I feel we are friends, but there are signs that say maybe we are more. So I am confused what do I do?
