I heard a song that I think is from a Broadway show, but I'm not positive about that. It's kind of a slow song in a minor key. A guy is singing to a woman he loves while acknowledging she doesn't love him. He's suggesting they live together only because it's convenient and he doesn't expect her to love him. He'll make dinner. It's something about a convenient relationship (?) I think. I've tried googling but without success. Any ideas? Thanks in advance!
