The traditional purpose of a Greek chorus was to be "the perfect spectator" to a drama. They didn't engage; they just witnessed a drama, and were given a pause in the action where they were meant to inform, or reflect, what an audience should feel or think. But they were not to engage with the characters; they simply witnessed. A husband, by contrast, should be an active partner; a person with his own thoughts and feelings, who engages with his partner. So, to tell someone they need a Greek chorus, not a husband, means they (basically) want someone to witness drama, not to engage as an actual partner or active character in someone's life.
