She's 92 effing years old. She's not all there. She's not some mother in law godzilla, her mind is deteriorating and she can not sense or reason the way she used to. And she is your bf's mother, NOT yours. If you spent an entire lifetime kissing her behind, go ahead and belittle her in her dying days. But you have absolutely no say in the care for your boyfriend's dying mom. That is just plain cruel and awful to treat someone that way, no matter how abusive she may seem. Being an adult is sucking it up and playing nice no matter how you feel inside. That is just outrageously cruel to do to someone who is deteriorating and dying.
