Have you talked to your sister in law about it? It doesn’t sound she’s taking part of all this drama, so I’m curious how she feels about all of it. Would imagine she might be hurt that her family is trying to project a different life for her, showing the world what they wish her life was. If she’s upset about it too, she might be better able to stop the behavior than you. And if not, at least understand that someone else is similarly annoyed by it all might make it more bearable- misery loves company.
