Reply To: Am I being unreasonable?

He’s right, this is how she is, and she’s bonkers and awful. It sounds like you’re still trying to interact with her like she’s a regular person and taking her reactions personally. That’s a recipe for insanity because literally this is how she is to everyone and she’s not going to change. So yes, take yourself out of the picture. Any interactions you have to have with her, keep them brief, informative, friendly, and factual, but interact with her as little as possible. She is your partner’s problem not yours. But if his lack of boundaries with her is becoming your problem, then you need to discuss it as a couple.
