Every time I visit my wife in the memory care unit she wants to come home. She has been there for 4 1/2 years and has never got used to being there. She says she can't unterstand why she can't come home because she is doing great. I don't know how to answer and have tried every answer I can think of as to why she can't come home, but of course she doesn't understand. What can I tell her? When I leave she is crying and that breaks my heart.
