I wouln't call you a jerk either, but I think I'm hearing your request loud and clear. So....
STOP behaving like a damn fool! At what point in your life did you decide the only thing missing is a man who doesn't cheat too much? He had his shot with you and HE blew it. Now, since he's no longer interested you're allowing yourself to fall into the I-want-what-I-can't-have quagmire, without even considering that a cheater isn't something you've ever wanted. STOP IT!
Now, it's Thursday morning and you have a plan to make. You are going to go to your favorite boutique and tell the sales girl "Make me sexy. I want to look beautiful". A hair cut, manicure, pedicure, massage, maybe even a makeover wouldn't hurt either. Let your budget be your guide (but splurge a little).
Now that you're looking fantastic, and make no mistake, YOU DO, head on down to the biggest dance club near you THIS Saturday Night and turn down man after man after man until you either meet one you like or decide your ego just can't take any more fluffing.
Either that, or continue moping about because you were denied your chance to spend 5 out of 7 days each week wondering who your husband's sleeping with.
Now choose. Choose wisely!
