Granny needs to move into a home.

But don't blame your wife for making bad decisions if you didn't chime in. If it is an equal partnership, you don't just accept what the other person plans if it is a bad idea. You discuss options and you decide from amongst them together.

If you passively allow something, you are still a part of the decision-making process. Everything is as much on your head as it is on hers so don't pass that buck.

But Granny needs to go. I don't see any other way. It is simply too much for your wife to cope with.
