Zelmo, I just finished reading the rest of your other thread (the one that Mark linked to this one). It seems that you may be misinterpreting something about the gender distinction. I don't believe Dr. Harley intended to say that infidelity is harder on women than men. The quotes that ML referred you to were talking about Plan A being harder on women than men. Again, I believe this to be consistent with the gender differences Mark has tried to explain and the media takes advantage of.
