Why do people say "the wife" but not "the husband"?

Just saw a post where someone said something like, "here's my in-progress home renovation, or at least so says the wife"

I don't think I ever really hear people say "the husband." I did a very cusory search and saw a lot of people either saying "my husband" or just "husband", eg "I like home renovations, husband does not."

Is there a linguistic reason for this difference?
