Anybody know the name of this song?

I caught the end of it while driving to work. It sounds like it's probably Hip-Hop or R&B. A guy is singing and the lyrics i heard are like this "And she said I try to run away but I can't run away from you" something like that. Or at least thats the gist of what he's saying.

Those aren't the exact lyrics cause I googled, yahooed, and binged it and nothing came up. Anybody have any ideas?
