My MIL moved in several months ago after selling her home and most of her things due to her overspending and debt. She came out on the plus side of it and is living with us. She has already depleted her money from the home sale within only a few months. My husband and I have spoken with her many times (and yelled) but she continues. We cannot have her declared incompetent bcz she is able to drive and care for herself. We can not afford to take her expenses on and she still needs to pay for things. What can we do?
