Women why do you still hold on to the belief that your man will not cheat?

Why is this women? these days women are as ual liberated as ever, which means it is not hard to find a quick hook up. so in essence all this new discovered ual liberation by modern day women is more of a curse then blessing. The reason why im sure every man in a relationship has cheated is because its in our nature and these days its so easy to get a quick fling. women just look at it like this, If Brad Pitt asked any women in a relationship to cheat on her man with him 99% of you would agree, well to a man any attractive women is our Brad Pitt! so in reality men will cheat regardless of how beautiful his girlfriend is if he has the chance. so why are young women, so niave and still believe there man will be faithful????????
