I really don’t think anyone could give you the answer you are looking for. It depends on the spouse that is left, and how dependent or independent they are. TV is easy to handle a house, because you can hire a reputable company to fix it.
Some will stay due to activities here. Some for friends, or if they are a veteran because there is a clinic here.
Then there is the spouse who came to make the other happy, and would leave to go back to family.
But I will say if you are a male, your chances of being well fed, and have a active social life is pretty good.
I don’t think the decision you are looking for, really could be made until the time has come. Pre planning could only change once realizing how much your life just changed
