What decision does Nora make in the end?

Nora, seeing Torvald’s true character for the first time, sits her husband down to tell him that she is leaving him. After he protests, she explains that he does not love her—and, after tonight, she does not love him. She tells him that, given the suffocating life she has led until now, she owes it to herself to become fully independent and to explore her own character and the world for herself. As she leaves, she reveals to Torvald that she hopes that a “miracle” might occur: that one day, they might be able to unite in real wedlock. The play ends with the door slamming on her way out.
