This man knows what he's talking about ;)

RebecaJust / 우리 남편 sounds more Korean yet 제 남편 is also grammatically perfect

Korean American or young Korean woman would say 제 남편 as she lives in the individualist culture

A typical Korean wife would say 우리 남편 as Korea is a collectivist culture. (We I)

우리 is used as 'my' usually for people and object that we feel sympathy or affection towards. Since the hubby is sleeping on the couch, he is no longer a subject of sympathy for this time :D

Just kidding. 제, 내, 우리 all interchangable (though 내 is the least polite among them)
