Rhett mocks everything again, covering up any indication he may have given that she hurt his feelings with her deception. However, he makes a point of asking Scarlett if she’s gone to any other men besides him. This suggests that he does care something for Scarlett, and believes she cares something for him. He then covers this up by telling her to be more submissive and ladylike next time—an instruction Ellen would’ve given her to get a man to propose. Note too that Scarlett accuses Rhett of
allowing her to humiliate herself—she’s unwilling to accept responsibility for her own actions, another sign of her self-centeredness.
