What's the point of rubbing anyone's face in anything? 99% of the time nothing good will come from doing so, only stir a pot that doesn't needs stirring and enticing the other party to respond in kind... can you see where this will deteriorate into an unnecessary battle based on past grievances that are best left in the past?

You've broken up, divorced or otherwise parted ways, seeking vengeance is really just dwelling on a past that made you unhappy. why carry the anger, rage and pain of that past when it does nothing to enhance the relationship or date you're currently in?
