Take Me Back Home and Leave Me There

Pam Stephan wrote the following on the Alzheimer's Reading Room Facebook page. 

Dad has lived with us 7 years. Recently he says over and over "Take me back home and just leave me there." 
We maintain his house - its in another city - and Mom's ashes are there. He won't tolerate a hired person to stay with him. 
But today he said "Take me back home and just leave me there." so many times that I ran away and am holed up behind a closed door now.

How should I respond to him, when he says that phrase? I'm quite frustrated.
