In "The Story of An Hour" we meet Mrs. Mallard. At the beginning of the story, she finds out that her husband is dead, and although she feels some sadness, her immediate reaction is one of happiness at the thought of being free. She thinks of the significance that this has for her life and her identity, and how she will now be allowed to explore the world as an independent person. Mrs. Mallard had never thought of similar things before, and she also never thought of asking for a divorce.
I'm not sure what the question is here, but this is not true. While she was unhappy in her marriage to her husband because she did not feel as though she was free to live for herself, she was not going to ask for a divorce.
