You're not an awful person; you are providing a service.
In my eyes, I'd work with the one who contacted me first, or who I knew, and pass the spouse off to a good realtor friend (thinking of 2 who could handle this now). That way, I could fully represent "my" customer without having to try to impartially represent the person as well. And if asked, I'd tell them each my reasoning.
