"Based on my research," the gender studies professor says, "I believe that 60 percent of women will at some point in their marriage embark on an extramarital affair."
Barash interviewed 500 women nationwide and found 75 percent lie about how much money they spend, while more than 60 percent admitted to cheating on their husband.

This is the question for "Dear Abby" advice column:
I have been married for over 11 years. My marriage was a dream come true and appears to be ideal, with a loving husband, a big house, nice jobs, fancy vacations and now two children.
A twist of fate started seven years ago when I was reunited with an old friend from high school. Within a year we became intimate and very attached. We tried to stop seeing each other, but our separations wouldn't last.
Four years ago I got pregnant with my second child.
It turns out the child is not my husband's. My friend wanted me to divorce my husband but could only offer his love and companionship and not the marriage or lifestyle I now have.
I was scared of starting over in life. My secret relationship and all communication with my friend ended shortly after I gave birth. No one has any idea of our affair.
I recently was in contact with him after 2 1/2 years. We still love each other, and I don't think I can live without him. I feel so guilty about my feelings that I cause a lot of arguments in my marriage. I mentioned divorce to my husband, so now we see a marriage counselor. It has been helping.
The problem is the entire story isn't out in the open. I know I really messed up. Help!
