I have dated both. I actually prefer Greek men cause GDI's usually don't have any concept of how much time we spend doing the work of our organizations and are more prone to get jealous or argue about your time committement with your org. Of course that is not to say that Greek men won't either...cause I have had that happen too...but in the end it shouldn't be about what letters that person wears or doesn't wear but about how they make you feel and how much you care about them.
