GIRLS WHAT DO U THINK...?

Well this girl I,really like supossidly has a boyfriend. But last week she walked right by him in the car and he was the only one in line. Didn't even say hi or sit near eachother.and today she only said hi but he sat at a table way far away. Well I'm uber shy and wanna talk to her but idle how to if she might have a bf. They only had a wave hi not a hug and sat far awatly from eachother. By the way I'm a sophnore in high school. Oh and she always looks at me everytine in the hall. And its a stare kinda and at the last mass where she was in choir and I played guitar for. She looked back like four times at me and I caught her. And vice a versa she's not a partier like me. We both love john Mayer and music. And she's a great Singer and I'm a great guitarist. But yea she always looks at me everyday
