The bolded happened to my dad's best friend, the guy and his wife were a long-time married couple, raised four kids, doing well. When she turned late 60's she started to get dementia, within a few years, it turned into full Alsheimer's, he was forced to put her into the local nursing home, visiting her every day. After a few years, the bills started mounting up and he realized that he was going to be forced to sell their farm to continue to pay for his wife's bills. Went to a local attorney, and the guy told him he had 2 choices, sell the farm, or divorce his wife of over 50 years. He ended up divorcing his wife, created quite the scandal locally, but once word got out of the reason, most thought it was the right thing to do. He still visited his wife regularly, his kids were fine with it, and ended up with the farm, and the wife never knew the difference. Their son told us how he hated to go down and see his mother, when she could not even remember who he was.The tricky part about LTC is if both husband and wife are alive and one ends up in one of these places long term. This can quickly drain savings. My work has seminars for people over 50 and this was one of the topics. They gave three different options and the best option that they mentioned was a special kind of annuity(immediate) that the government couldn't come after. I don't remember all the details.
Old age sucks, buts it better than the alternative.
