Thank you everyone for the replys. Montana is home and I'm not sure anyplace could compare.
We're still working it out, wife's dad won't leave Oklahoma but the wife wants to be closer to him. I won't leave mountains. So we're weiging options on compromise.
Nothing is set, I'm just looking at possible options. Thank you again and keep the responses coming.
I was wondering if this was the case. Not 100% sure of your situation, but I will say this - when my mom needed to go into dementia care, my dad (about 80 at the time) was ADAMANT it was unnecessary and that he could take care of her as he had been doing so quite well for a few years as she declined. There came a point where he would not listen to anyone, including the nurses about it. That was until one day we all met at the nursing home and I essentially let him know he was no longer able to make the best decisions for my mom and that she would be going to get proper care - whether he liked it or not. He relented. The problem was his pride, and what he felt was a failure as a husband. He said had taken care of her for 60 years and would continue to do so. I told him that by getting my mom proper care was the best way to continue to be a good husband.
Less than a week later he came to me and told me how making the decision for him was the best and most correct thing for my mom and him. He had gotten more than 2-3 hours of sleep - more than in almost a year (he was constantly up chasing my mom), and was coming to terms with reality.
That's a long-winded way to say that sometimes, when a person is no longer able to make decisions for themselves or they require a lot of care, their intransigence about things is often driven by unrealistic things, often psychological (I was born here, and I'll die here!). It takes some frank conversations with them so they know that at some point they have to trust YOU now to make the decisions. It's inevitable. Now, several years after my mom has died, my dad will often say how much he appreciated me stepping in and just doing stuff for him - even financial - (i have full power of attorney, etc) as only in hindsight does he see that he was truly incapable of making those decisions. I have had frank conversations about moving him out here when he gets where he needs close care. He knows that at the end of the day, we can't simply relocate three jobs, a college, and a house because he wants to keep living by the beach. Stability for everyone is super important, and if you lose stability by moving - what is gained? He gets it.
Anyway, not sure if any of that applies, but good luck as things develop. I would look at it this way - if, given you and your wife's situation, it is possible to support him where you are, I would start that conversation with your wife and him asap. Plant the seed, etc. "You know, if we need to take care of you, we'll be able to do it best in Montana, etc."
