The Rage Rules:
  1. You are allowed to hate the other woman on the day you find out about her. It might not be rational, or fair, or feminist, but you just got cheated on. You can hate EVERYONE today. Talk crap about a woman you don’t even know to your friends and imagine drop-kicking her while you burn off some major rage calories at the gym.
  2. During this initial Day o' Hatred, your anger must be kept to imaginary revenge. You will not throw eggs at her house or call her a slut on Facebook.
  3. However, after the initial period of pure rage, you must remember that your boyfriend betrayed you, not this girl. Crap-talking (about her, anyway) must cease. You may still secretly, unfairly resent her for up to one month.
  4. If you discover that she had no idea you existed, you must cease hating her immediately. Seriously, she got duped too. You don't actually have to become best friends, but you're misplacing the blame if you're still hoping she gets an incurable case of acne.
  5. If she knew about you and purposely helped your boyfriend sneakaround behind your back, OK fine. You can hate her a little. That wasn't cool. But remember that it was still the guy who ultimately betrayed you. Also, all that negativity will only hurt you and give you frown lines, so probably you should just let it go anyway.
