I was "the other woman" and when the "s---" hit the fan it really stunk things up.
RUN as fast as you can. Grieving the loss is a whole lot better than living with the end results. The man I was seeing cheated on the women he was cheating on his wife with--even has a kid or two running around. Don't fall for his "I would never do that to you" line cause he's already doing it. white_iris
