He's Just Not That Into You

Greg Behrendt freely admits that he was a jerk to women in his former life. But when he met his wife he stepped up to the plate, because she raised the bar and demanded that he become a better man. As a brother, a friend and a reformed jerk, Greg has had plenty of experience shedding light onto guys' behavior for women, but a lunchtime conversation while he was writing for HBO's Sex and the City sparked the idea behind He's Just Not That Into You.

A female co-worker asked Greg why he thought a guy who didn't want to come up to her place after a date would e-mail her two days later. "I just said, 'I don't want to do this. I feel odd about it. But he's just not that into you,'" Greg recalls. "And then sparks flew! All of a sudden the stories were flying. Everybody had a story. Everybody wanted to know."

So, we asked Greg to tell women the absolute "in your face" truth about their dating dilemmas and everyone agreed to hear it.
