My mother needs assisted living but my sister wants her to continue to live with her so my mother can pay her mortgage. How can I deal with this?
Maybe you can talk to your sister about how not having the responsibility of caring for your mother will free up some of her money and it will all equal out. Less food to buy, more time to work, one less person in the house using electricity and water, for example.
No one knows how hard it is to take care of an elderly parent and should be grateful if a sibling wants to care for mom it is the best place mom can be especially if that is where mom wants to be. Believe me it is well worth mom paying the mortgage and car payment. I think there is some jealousy here.
