Thank you, everyone, for your prayers and suggestions. Karen is working with a wonderful financial assistant/adviser with the hospital. Before this latest relapse his bills were over $500,000, of which below $50,000 was paid out of pocket. They were saving that money to move to Colorado some day.
Since moving back to CO is my plan as well, I casually suggested we buy a duplex and the four of us (me, my BF, Karen and Jim) take care of each other. Before Jim went back to the hospital, my BF had mentioned K&J staying with us after we move; I threw in the duplex idea. Karen didn't laugh; she said my BF might be on to something. I wanted to never have a unit number in my address ever again, but I'd do it if this happened.
