Did you read the bottle's label? Probably says, "Refrigerate After Opening".
Now the manufacturer may be over cautious or run by their legal depart or the FDA but it still recommend frigeration.
Plus a running difference of 49 years about ketchup/catsup with one's wife just isn't worth it, is it?
Now if you're complaining that your wife is a controlling female-dog, that's different. That I understand differently.
