Does this girl like me in general?

I've known this girl ever since fourth grade. During that time when we had lunch, she would sit next to me even if there was no space for her to sit. When it was recess, she will come join me when I play basketball. If I say no, she will pout. Now that we are in middle school, we do not communicate that often. I see her enjoying her time with other popular boys in school. However, I see her glancing at me at times.
