I know there it's really rude to uninvite someone to your wedding. But there has to be a line of extreme behavior when it would be okay. Like you just saw your cousin's husband on to catch a predator. Or your sister in law stole your identity. I think my aunt crossed that line, she slapped a random neighbor kid about 10 years old for swearing. Now FI doesn't want some crazy lady around his daughter at the wedding. I can't blame him. By the way my aunt already said she isn't coming to the wedding, and she has no manners. But if I send her an invitation to just be nice. She can still change her mind and show up. So should I just save postage and not bother with sending her an invite. If she asks I'll tell her the truth. But I don't speak with her often.
