It would be safe to argue that Nora's relationship to the various men in the play is almost predictable. Nora is a woman groomed to be a sort of conversation piece rather than a wife and mother.
The way she talks, the way she conducts herself, and the manner in which she expresses her emotions are typical of a woman whose sole purpose in life is to please everybody.
We can also argue that this desire is, indeed, altruistic. She really does not expect anything in return, except the natural desire that good people wish to receive by witnessing how their choices helped others. However, nowhere in the play can we get any form of proof that she gets even that much.
When she helped her father, he died. When she risked her dignity to help Torvald, he rejected her. When she complied with the requirements that Krogstad put upon her, he laughed at her. Even when she counseled Dr. Rank and tried to make him feel better, he simply isolated himself.
Therefore, we can conclude that Nora's relationship to the different men in her life is primarily aimed to be a nurturer and a support system. Sadly for her, society has another thing coming. She ends up leaving, wondering what else life could have in stock for a woman like her.
