How does the Author depict a high class marridge of 19th century?

Louise doesn't have a bad life. Her marriage was not oppressive. The author gives us a sense that it was a marriage made out of expectation. Louise lives in her husband's world by reason of her gender. It was a union made out of what people were supposed to do at the time. There is no financial or physical/mental struggle that the couple had to overcome together. There hence does not seem to be a deep meaning connected to it. Louise simply dreams of freedom, perhaps self-discovery of an identity separate from her husband.
