Sadly, one spouse will die before the other someday. My mother just died two months ago. (Needless to say, the holidays were not happy- thank goodness last year is over.) My dad is having a really difficult time. He's very lucky that he has children & grandchildren & friends who have invited him over for dinner, etc., to keep him company. But it's still incredibly lonely & hard for someone to live in a home where there wife suddenly isn't there, where the person with whom he shared every part of his life (including his business) is gone, & everything he sees reminds him of that. I wish he could move, but he can't with the crisis this country is experiencing. I think that it's a good thing that you're worried about what will happen now, b/c you can take steps to be ready. Develop interests & hobbies that you can do by yourself. Things would be much easier for my dad if he had done that. That's the best advice I can give you. I'm trying to do that for myself, b/c I'm getting old & I don't have a husband. So consider yourself lucky to have your wife & enjoy her now, as Lynne wrote.
