Song to dedicate to his jealous ex?

Your Fiance's ex is a sad creature who is only hurting her child and I do not think you should react to her in any way. Do not acknowledge her presence. If you respond with the song, she can point to it as a form of harment in court. As tough as it may seem, you will be better served ignoring her, the judge will admire your restraint. Good luck, I hope the judge rules in your favor and can get the ex to behave herself.
