Is there anyway I can rekindle an old flame?

I hooked up with this girl at my school last year, back when i didn't know about any of this, and pretty much gave her all the power because i turned into a needy freak and basically was hanging on her every word. I just added her on facebook, and I really would like to be with her because she's genuinely interesting, not just attractive. I don't want a relationship, but i'd like to change the dynamic so that i'm in control.

Any advice as to how to go about doing this?
