Emma Bovary in Madame Bovary (1856) spent her childhood immersed in Romantic fiction. As a result, she’s expecting that her husband will be someone who understands her soul perfectly.
When she does get married to the kind, thoughtful but human. But she is quickly bored by the routines of married life. She is convinced that her life has gone profoundly wrong for one central reason: because it’s so different from what the novels she knows told her it would be.
