Why does Nora Helmer leave?

Nora Helmer leaves her husband, Torvald, at the end of Henrik Ibsen's play "A Doll's House" to seek independence and self-discovery. She realizes that her marriage has been based on superficiality and that she has been treated more like a child than an equal partner. By leaving, Nora asserts her need for personal freedom and the opportunity to understand her own identity beyond the roles imposed by society and her marriage. This bold decision symbolizes her rejection of societal norms and her desire for authentic self-fulfillment.
