Was leaving the best choice?

It is obvious to the reader within the first few pages of the play that Nora is not the superior in this household. Her husband Torvald calls her demeaning names such as "lark" or "squirrel" and she seems to push it off as if it does not matter. For nearly the entire play she is allowing others to think for her and at the end, when she finally brings about ideas of her own, she leaves. This occurrence struck me as very strange. She has finally revealed her deepest secret to Torvald, who minutes later forgives her and at the time of her departure has already offered to change for her and respect her more. At the time of her departure Torvald has already offered to change for her as proved by his statement, "I have the strength to make myself over."(Ibsen 113) At this point in the story I felt a shift in power. Nora has changed from her carefree, spendthrift ways to a seemingly more confident and knowledgeable woman just by discovering and acting upon her current situation. She however, seeing her husband begging for her to stay, should have seized control, demanded more authority in decisions, and dropped the previous restrictions placed on her outside the house. It seems rash and selfish to leave her children when she could have easily stayed. I found myself slightly disappointed with the ending involving her withdrawal from her family and I think several options could have worked to achieve her goal of education and control, better than the one she chose.
