Cheating In Ernest Hemingway's The Awakening

At the beginning of this novel and for the first several chapters, I saw Edna as a strong woman who wasn’t afraid to stand up for herself. Specifically, the fact that she was unhappy in her marriage. As we know, in the time set in the story it was exceedingly difficult to get a divorce especially when the reason is that the woman is unhappy. As sad as it sounds, that’s the way it was. As time went on, however, it became apparent that Edna always seemed to want something more. When she became infatuated with Robert, I was not necessarily surprised but rather dissapointed. In my opinion, cheating on your spouse behind their back is a horrible, immature action.
Later in the story, when Robert leaves and Edna realizes that he is no longer an option,

she takes the next best thing she can get: Alcee. Furthermore, it is very clear late in the story that not only does Edna not love her husband, she doesn’t particularly care for her kids either. This is the number one thing I have a hard time understanding. It simply doesn’t make any sense to me how a mother can not love her own children.
For these reasons, I did not like Edna’s character. She seemed to never like what she had and always wanted something better. Finally, Edna’s suicide was the ultimate cowardly action. Her life was not perfect, however a series of poor decisions left her in a place that she felt it was too hard to get out of. Leonce was never abusive, and there were other ways to solve her problems than moping around and cheating on him. I feel that Edna was not a strong person. She made immature decisions and in the end took the easy way out, leaving behind people who cared about her.
