I know the Rambam says a wife should view her husband as a king (Hilchos issues 15:20). Are you aware of a place where the Rambam says he should view her as a queen?
The Rambam says in the halacha before this, before talking about what the wife has to do for her husband, what the husband has to do for his wife. He writes that at that he should honor her, “more than himself”, meaning that he should by her things in a higher standard than what he would by for himself. If he is treated like a king, and he is treating her better than what he would do for himself, then she is a queen.
