Regarding the Quora link and Spanish, the word for spouse is feminine for wife (esposa) and masculine for husband (esposo) so it’s not the same as the word spouse in English in my opinion. Feminine spouse is wife, isn’t it?
There is an addition word in Spanish, marido, which means husband.
Moreover, you can use mujer in the same way you would use it in English, as in my woman to describe your wife.
At a wedding you would typically be pronounced Marido y Mujer. Husband and woman. Which is interesting since in English it was for a long time man and wife, and was update to husband and wife. Or, I consider it an update. I would guess both are still used.
Extra note: esposas means handcuffs.
