Some people like your niece are naive or choose to not acknowledge that someones behavior is wrong. Many many other people at that wedding think your H was behaving like a jackass.
Now is the perfect opportunity to show what a classy woman you are and not to react to his awful behavior.
Focus on you and your kids
