I have two friends that are currently not speaking to each other. Friend 1, Friend 2 and The Guy all met in grad school. Friend 1 and The Guy dated for a few months. Fast forward six years later and Friend 1 is married and expecting a baby this fall and Friend 2 and The Guy just started dating late last year....after years of being just friends. Friend 1 is so upset and will bad mouth them any chance she can get!!!! Drama!

Have you ever dated a friend's ex? How did it go? Did you and friends have any guidelines about this?
