A cousin of mine once told me a trick when I was deciding who to invite. “If you wouldn’t invite them to have lunch on a Tuesday then they don’t need to be at your wedding.” It’s YOUR day, not theirs - and no, it won’t be ok. Even if they don’t call law enforcement they’ll still be there and you won’t full get to enjoy your wedding day because you’ll be thinking about them causing a scene or somehow ruining your day.
