OK I REALLY like this girl...?

Well I'm in the seventh grade and I'm crazy in love with her. She is beautiful. And when I see a huge crowd of people, a light shines on her. Ive liked her since 4th grade. I impress ALL the time and she knows I love her. But we have went out like 2 times. I even tole her that I loved her. And my first slowdance was in 6th grade and it was with her, it was one of the happiest moments in my life. Sometimes i look at her then she looks at me then i don't look at her because i dont want her knowing that im looking at her. I'd do everything and anythnig for her. So how do I make her like me ???
