ACT II

In act II, a lot of things took place, and a lot of things were discovered. Nora tried to convince Torvald to save Krogstad's job. Because of Mrs.Linde, Krogstad fears losing his position at the bank, Torvald says that Krogstad is an embarrassment basically because of his bad reputation. Which actually, Nora is doing the same thing that Krogstad did in his past. Which would mean Nora is no better than Torvald, for being a liar and forging signatures.
Also, Nora flirts with Dr. Rank and shows him her stockings. Personally, I think Nora was wrong, and I think she has been leading him on for the longest time now. Soon after, Nora finds out that Dr. Rank likes her. Nora probably didn't purposely mean to lead on Dr. Rank; perhaps she just has a flirtatious personality with men. However, she could have known that Dr. Rank liked her because there are usually signs. Nora is simply playing with Dr. Rank's emotions, which isn’t right at all.
Also, Krogstad decides to tell Torvald everything in a letter, and put it in the letterbox. From the moment she finds out of this, she tries to prevent Torvald from seeing it. Although, she wants the truth to come out, she doesn't want it to be from anyone else. Nora should have told her husband before she was exposed and the truth came out. I believe that eventually, the truth will come out, one way or another. It probably is going to be excruciating when Torvald finds out, because their whole marriage has been based on a lie.
Torvald must think Nora may be intolerable at times, but he still loves her. Whatever happens to Nora when Torvald find outs, I believe it is fair retribution because of her building up of lies. The situation could've been dealt with much better than him having to find out on his own. I think it would've been more mature for Nora to simply tell her husband on her own. Sometimes, when you just tell the truth, the person respects you more in the end, rather than not telling the person at all and thinking that protects them, they may resent you for it. A lie can hurt much more than the truth does in the end.
