“Pulling her up” about her behaviour makes it sound as if you think you have some kind of authority to admonish her. Like a parent with a child. You’re not in that position. Our in-laws have never been our children and even our children are now adults responsible for their own behaviour.
You were a guest that was treated badly by a host so what steps would you take if it was, say, a neighbour whose husband ignored you. Would you think you had the right to “pull him up” or would you just think how rude and ignore him.
I am assuming you were an invited guest and didn’t just suppose it was ok for you to visit as part of your Christmas Day “family round”.
This with bells on.
However, when your anger cools I think a heart to heart would be a good idea. I’m not talking about a list of grievances to present. I’m talking about a conversation that is 2-ways, calm, with you coming into it with an open mind. Her rudeness is rooted in immaturity, as she clearly is not in control of her emotions if she can go out of her way to be rude.
However, that doesn’t mean she may not have legitimate issues with you and certain family members. Be open to the fact that an escalation in her behavior may be a reflection of her also coming to her wits end with your family as well. Rare is the instance where these situations are without abrasion coming from both sides. Only open, adult communication can get to the bottom of it. I am also not describing complaining to your son about her. That will backfire, and it should. You are her mother in law. As the elder, I would be the one to break the ice. Initiate the conversation when enough time has passed. If she rejects the opportunity to talk, rest your mind knowing you were the bigger person. Then smile sweetly and match her demeanor.
