Ex-Etiquette: Keep big announcements apart from child's birthday Q Is it bad ex-etiquette for an ex/co-parent to use a child's birthday party to propose, announce an engagement or pregnancy with the new partner? i.e. guests sing happy birthday, candles are blown out and ex takes center stage and say, 'While you are all here...'? And, if you are faced with this, what the heck do you do?
