I think I'm in love with a girl.

She a popular girl and very gorgeous that every boy in the school has a huge crush on and we are in the same math class. She always stares at me and tries to go near me. And I think she gets nervous when I'm around her. But she always tries to impress me for some reason. She tries to be funny around me. I think I'm in love with her but at the same time I want to be careful because she is a popular girl.
