Does the girl I have a crush on like me?

well DUH of COURSE she like you. You're right about being clueless :P Give her time and when you think she ready ask her on a date. Or you can just ask if she wants to hang out after school with you and a few friends and then FLIRT. Only time can heal a broken heart but she seem to REALLY like you and she gave off some MAJOR signs so hurry up and ask her out already before you lose you chance. Good luck!!!!!
