text_A: Nora tells Torvald that she is leaving him, and in a confrontational scene expresses her sense of betrayal and disillusionment. She says he has never loved her, they have become strangers to each other. She feels betrayed by his response to the scandal involving Krogstad, and she says she must get away to understand herself. 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. Torvald insists that she fulfill her duty as a wife and mother, but Nora says that she has duties to herself that are just as important, 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 can now confirm that Torvald is the kind of person she had suspected he will be and that their marriage has been based on mutual fantasies and misunderstandings.
text_B: Was Nora unsure of Torvard's personality?
YES.
