I'd agree with SFTS, but if you really can't move on at all, there is no use in sitting by. If it's obvious the friendship is too awkward, you might as well ask once more. If you get a yes, great, if you get a no, you finally have closure. Don't talk to her anymore unless she talks to you.(in other words dont be mean, but just dont mess around if you dont have to).

best of luck
