Uninvite the whole damn work group, if they are insufficiently shocked about this - actually, write them off anyway, they decided a wedding invitation was grounds for shunning and professional sabotage without even asking if there was another side of the story.

Something very creepy is going on there, but it's not your job to fix it, so resist getting drawn further in.)
