While it may relieve some frustration for a short time speaking negatively about a soon to be ex is in poor taste. Even worse then speaking negatively is broadcasting it on social media. By making your soon to beex look bad on Facebook, you could actually be making yourself look worse. Also be careful of throwing your new “single life” in the face of your soon to be former spouse. Pictures speak louder than words especially in custody battles! Final word : Do not disparage!
