If anyone of you noticed a poll on facebook, you'll find an answer to this thread:
"A woman needs a reason to cheat and a man just needs a woman"
So the bottom line is that if a man is unfaithful, then feel free to cheat on him to get even.
And BTW, don't forget to watch the movie "Unfaithful" starring Diane Lange.
ahem, would you mind letting me know what reason does a women want in order to cheat on there men...?
