Yvonne, I really hate to be the one to break this to you ( ) . . . but just because an A-plot is tightly intertwined with the B-plot does not mean it isn't there.
Do you know the most surprising thing about divorce? It doesn't actually kill you, like a bullet to the heart or a head-on car wreck. It should. When someone you've promised to cherish till death do you part says, "I never loved you," it should kill you instantly.
