Why does Nora feel that her final decision is necessary?

Nora realizes that, before she can be a wife, she must first discover herself in the world. She leaves as an awakened soul, determined to become a full person rather than the doll of the male figures in her life. Thus, it is important to note that Nora’s motives are not simply idealistic. She does not know yet whether she should adhere to religion or morality or virtue, but she knows that she must escape the oppressive situation in order to figure out what to do next.
