I just think you really do owe it to yourself to go out w/a few other girls, just to see how it is. If you're still thinking about this girl while you're out to dinner w/another, then you know where your heart is. Also, drop a couple lines to the girl at work about your date last night w/so-and-so. Maybe if SHE sees you're not willing to wait around forever, she'll get on her horse and start making things happen.
