In the 19th century Nora leaving her family is seen as impossible as Nora
has a duty to her children and her husband. Today it is seen to be more
acceptable and happens to families. In my opinion her action at the end is a
childish self centred decision as the only time her and her husband have a real
conversation about their marriage is when she decided to leave. And she has not
tried to bring this up with her husband to work at their marriage. And so her
decision to leave her children and find love and happiness elsewhere is
childish as a marriage and family take work and she thinks that is she starts
again with a new life and she thinks she will find love and happiness but all
she would have to do is find happiness with her children. She does not have to
be with her husband but at least see her children and this might have been more
acceptable in the 19th century than leaving completely and also talking to her
husband to sort things out instead of just leaving is also socially more
acceptable. But because she is self centred she does not see any other option
as the others involve work, understanding and courage to stand up to her
husband instead of be cowardly and leaving.
