What to say when your girlfriend asks you why your going out with her?

Tell her that she makes you want to be a better person. I know it sounds cheesy and is sort of a line out of "As Good as it Gets," but that is the best answer I can think of, without sounding creepy, ridiculous, or desperate, or worse, obsessive, especially if it is somehow true.
