I'm thinking of cutting off my mother because she wants me to divorce my wife even though she's pregnant and it's not mine.
Why do you feel like you need to cut her off, though?
She's constantly interfered in my marriage and has caused so much unnecessary stress.
Consider that by cutting off your mother, you're sort of doing the same thing she's asking you to do to you wife? I totally get why you feel the way you do. But underneath your anger, you might find a better solution built around communication.
I can't do that. She is my mother, but she refuses to listen.
I understand. I'm sorry you're going through all of this at once.
