The nice thing about dating a Greek man is that he understands your commitment to your sorority and won't have a cow when you tell him you can't see him for a weekend because of a sister retreat.
The bad thing is that he probably does have more access to women than the average Joe College...but this largely depends on the campus. Heaven knows a guy doesn't have to be Greek to be a total horndog!
Making ANY relationship work in college is hard, no matter your affiliation or lack of same!
