I still really like this girl...?

So about 3 or 4 months ago I asked this girl out stupidly over face book chat because I was scared of rejection.... I know that was dumb but anyways, We did not really know each other. Now I would not consider her a friend maybe kind of. So in my language arts class I can sit in 2 spots. With 2 of my friends that are in the class or one of my friends thats a girl and than the girl i like (they both are friends). Now I mostly sit with my friends.Anyways I think she is kind of my friend. I sometimes have to wear glasses and dont like to and they like to draw on the case..XD. Anyways I talk to her a little. She sits next to the table in front of me in science. Her friend sits next to me in science ( a different friend ). I am not really friends with her friend yet i laugh at the girl I like and her friend alot. I only hang out with them since the teachers moved us there. The girl I like is in my gym class and I am not the most athletic person.. Today in gym my coach paired people up and I was against her. I know we both suck at serving. She talks to me a little. I still really like her.. Should I get over it or ask her out? I like being slight friends with her though. I know last year I asked someone out and they could not go to the dance because of a dance competition or something. We didn't talk much. I still like her also. Should I wait until high school? I am in 7th grade. I am also not that popular.
