You're clearly too young and clueless to persue a relationship.
I'd offer you advice, but judging by how you type, and the way that the situation you described played out, it just seems like you're not completely sure of what it means to want, or date, a girl.
Perhaps you should forget about it, learn how to download porn and wait a few years. Trust me, you have all of high school to figure out how shitty the dating world is...don't be to eager. You'll just get hurt before your due time.
