I don't feel this is one bit ridiculous to refuse. She is a bottomless pit. You can't even get started with her. You are not wrong. You don't have to justify yourself. Fifty years old is old enough to know better and to do better. Even if you weren't ill, you would have the right to set a limit, and you would have a right to have peace in your own life. She owns her own life. She can live as she wants and is able. The thing is, if she crosses the line she will have her children taken from her, and that would be the right thing, in my book.
