My 89 yo mom has left her home to move in with my sister because her son, who lived in the home with her, is abusive but she’s too afraid to ask him to leave. She plans to live indefinitely with all her other children, there’s 4 of us, and refuses to consider a lodge or retirement community. She pays all of the expenses to keep her own home looked after so my brother can live there. He has both her vehicles at his disposal and she pays the insurance and registration even though she no longer drives. She expects to live for free and be looked after by the rest of us while she looks after our brother’s financial and housing needs.
