Doing that will lead to her moving on. Especially if your still in high school. Keep contact, but since you don't see her in school as often, use that as an excuse to go out more!
"Hey, i haven't seen you in a week and talked maybe once this week, lets go out to dinner!"
or call her sometimes, and if she asks why, just be like "just to chat".
theres a million things you can do in this situation! be creative.
--edit--
btdubz, i'm guessing you want to date her.
