Girls only! whaat should i do?!?

so theres this guy and we text alot and whenever we see each other at school we talk, and lately we've bin trying to hang out on weekends and stuff. We always flirt and joke around and make nicknames for each other and ALWAYS stay up late talking to each other. But neither of us has said anything about our feelings. i dont know if i should ask him or not! :s im scared that if i say anything it'll make it awkward if he doesnt feel the same. but im also scared that maybe he does like me and if i dont say somethin then ill be missin out on somethin great!! help please :) soo confused and dont know what to do.
