Hell Hath No Fury Like a Woman Scorned
Yes there were men who were dumb enough to cheat on women as beautiful, rich and famous as Halle Berry, Nicole Kidman and Sienna Miller!!!
This is not about being cheated on. This is about loving yourself. It doesn't matter how beautiful, smart, successful and wonderful you may be - there's always going to be someone who doesn't appreciate that. The only appreciation that you should rely on is your own.

It's so easy to become that insecure woman we all love to have. The one who starts to hate herself because of a man who broke her down. I have known some amazing women in my life, young, old, rich, poor, fat, thin, tall, short, blond or brunette - they all have a story of some guy who hurt them. Whether it was being cheated on, abused, ignored, lied to or left at the alter, it broke them and ultimately changed them.
Of course, my opinion is to find an immediate rebound because that guy, that relationship, the one that broke you - it was never about YOU. You were always the same smart, gorgeous and amazing woman. You weren't any less of who you are now with or without "that man".
