How Can I Get Her to Like Me?

There is this girl, Maia, who I have liked for a while. I text her a lot and she says I say the sweetest things. She knows I like her. Also, we are very good friends.The only problem is she is going out with someone. I know the kid she is going out with very well. He is my neighbor, I see him at school and football practice every day, and he is one of my best friends. I think I might love this girl. I see her all the time: at school, football games(she is a cheerleader), and i hang out with her sometimes outside of school. I get this weird feeling whenever I am around her: erflies in my stomach, I heat up, and get all nervous. What should i do, I want to get her to like me without hurting her boyfriend. Please help!
