Describe how Catherine felt about Heathcliff and her relationship with him.
Catherine loves Heathcliff, but their extreme class and social differences drive a wedge between them, in her mind. She soothes her conscience by telling herself that if she marries Edgar, who she does not love, she can help Heathcliff financially. However, not long after, Heathcliff makes a complete change, physically, at least. He is well dressed and his manners pleasant, and the two are overjoyed to see one another. However, something is not quite right and Catherine senses it.

"Although Heathcliff has the looks and manners of a gentleman, the revenge he plans is diabolical, and though she loves him, Cathy is not fooled. "He's a fierce, pitiless, wolfish man.… and he'd crush you, like a sparrow's egg," she tells an infatuated Isabella. When Cathy and Heathcliff meet for the last time, she tells him, "You and Edgar have broken my heart, Heathcliff! … I shall not be at peace." She dies two hours after midnight, having given birth to a "puny, seven months' child."
