I like her alot, but does she like me?

I know I posted about this a couple times, but I need more input...This girl and I have gotten pretty close, were in the same spanish cl together. I used to just say stuff in ping, and we were friendly, but we got closer, I add her on my facebook, I leave her a message, we keep talking back and forth, and i always look over at her in spanish cl, and she smiles, and gives those eyes. She's always bustin on me for sumthin, either in cl or on facebook, but in a joking way. Im not sure what to think. Ive been let down before, so I dont wanna get my hopes up again, but if people think I have a somewhat decent shot, then I will go all out for her. Anyones input/ suggestions would be greatly appreciated...she and i also love sports, shes a die hard yankee fan, im a die hard red sox fan...thats wen i knew i was in trouble falling for the enemy, cuz i have a personal vendetta against any yankee fan...we always give each other hard times about that...
