Herself is a strange word when you type is over and over. Herselfherselfherself
MIL is very pleasant and personable but when she sets her mind to something, watch out. You are a dinghy and she is a battleship - hard to stop and difficult to turn. Better to just get out of the way.
A month ago she had a nosebleed incident in the middle of the night that sent her to the hospital. It was a 5-hour ordeal, as most ER visits are, and she realized that although she was quite capable, she would be on her own if there was an immediate emergency. And so she has decided to move again, this time to an adult retirement community.
She is already packing.
