Act three[edit]
Kristine tells Krogstad that she only married her husband because she had no other means to support her sick mother and young siblings and that she has returned to offer him her love again. She believes that he would not have stooped to unethical behavior if he had not been devastated by her abandonment and been in dire financial straits. Krogstad is moved and offers to take back his letter to Torvald. However, Kristine decides that Torvald should know the truth for the sake of his and Nora's marriage.
After literally dragging Nora home from the party, Torvald goes to check his mail, but is interrupted by Dr. Rank, who has followed them. Dr. Rank chats for a while, conveying obliquely to Nora that this is a final goodbye, as he has determined that his death is near. Dr. Rank leaves, and Torvald retrieves his letters. As he reads them, Nora steels herself to take her life. Torvald confronts her with Krogstad's letter. Enraged, he declares that he is now completely in Krogstad's power – he must yield to Krogstad's demands and keep quiet about the whole affair. He berates Nora, calling her a dishonest and immoral woman and telling her that she is unfit to raise their children. He says that from now on their marriage will be only a matter of appearances.
A maid enters, delivering a letter to Nora. The letter is from Krogstad, yet Torvald demands to read the letter, taking it from Nora. Torvald exults that he is saved, as Krogstad has returned the incriminating bond, which Torvald immediately burns along with Krogstad's letters. He takes back his harsh words to his wife and tells her that he forgives her. Nora realizes that her husband is not the strong and gallant man she thought he was and that he truly loves himself more than he does her.
Torvald explains that, when a man has forgiven his wife, it makes him love her all the more since it reminds him that she is totally dependent on him, like a child. He dismisses the fact that Nora had to make the agonizing choice between her conscience and his health, and ignores her years of secret efforts to free them from the ensuing obligations and danger of loss of reputation. He preserves his peace of mind by thinking of the incident as a mere mistake that she made owing to her dumbness, one of her most endearing feminine traits.
We must come to a final settlement, Torvald. During eight whole years. . . we have never exchanged one serious word about serious things.
Nora, in Ibsen's A Doll's House (1879)
Nora tells Torvald that she is leaving him to live alone so that she can find out who she is and what she believes and decide what to do with her life. She says that she has been treated like a doll to play with for her whole life, first by her father and then by him. Concerned for the family reputation, Torvald insists that she fulfill her duty as a wife and mother, but Nora says that her first duties are to herself and that she cannot be a good mother or wife without learning to be more than a plaything. She reveals that she had expected that he would want to sacrifice his reputation for hers and that she had planned to kill herself to prevent him from doing so. She now realizes that Torvald is not at all the kind of person she had believed him to be and that their marriage has been based on mutual fantasies and misunderstanding.
Torvald is unable to comprehend Nora's point of view, since it contradicts all that he has been taught about the female mind throughout his life. Furthermore, he is so narcissistic that it is impossible for him to understand how he appears to her, as selfish, hypocritical and more concerned with public reputation than with actual morality. Nora leaves her keys and wedding ring and, as Torvald breaks down and begins to cry, baffled by what has happened, Nora leaves the house, slamming the door behind herself. She never comes back again.
