This one girl... (read description)?

Ok, I have been without a girlfriend for about four years now and i found a girl that i really like. Har name is Angela; we met at the middle of my freshman year in my english 1 cl, she sat in front of me. We talked and became friends and once i got to get to know her i started to like her more and more. Now she has me up in the middle of the night on my ipod asking you guys if this is a high-school fling or if it is the real deal. She is pretty, smart, and every time i make her laugh i feel really good inside. I am constantly thinking about her and i usually dream about her (daydreams and regular dreams) in my head i know her as the girl i am very interested in but from whqt i can see- she sees me as a friend. I haven't asked her out or anything and she doesnt even know that i like her. But i just really want to know; am i in love with this girl?
