Freeloading dad wants to add a freeloading wife

DEAR ABBY: My father has depended on my mother (and me) for money for as long as I can remember. It wasn’t because he was unable to work, but because he was lazy and had a drinking and gambling problem. My parents eventually divorced, and my father moved in with his sister (my aunt). She died in 2016, which would have made my father homeless, so my sister and I bought our aunt’s home from our cousins so he could stay there.
