We had to have this conversation with my Grandpa 2 years ago. He said there was NO WAY he was leaving his home unless it was in a body bag. There was much family upset. Finally, a few weeks later my uncle convinced him to just go look at an assisted living facility. Grandpa ended up thinking it looked like a pretty good idea and agreed to try it for the winter. By the time winter was over, he made no mention of wanting to leave.
I hopeyou find a way to work it out without too much stress.
