Answer: 2 Mrs. Mallard had loved her husband, but she is happy that she is free.
Explanation:
The title ''The Story of an Hour'' refers to the time period that has passed between Mrs. Mallard learning that her husband is dead, and discovering that he is alive. She is, at first, happy that she is finally free, but dies of a heart attack when she finds out that her husband is alive after all.
It would be wrong to claim that Mrs. Mallard hated her husband. In the story, it is mentioned that she sometimes loved him, but often did not. She is happy, but not because of the fact that he is dead, but because all the problems she faced in her complicated marriage suddenly disappeared, and her life became much more easier. She is not heartbroken that he is dead. In fact, she is literally heartbroken that he is alive after all, which results in her heart attack. She is not terrified to be alone, as freedom is what she has probably wanted for a long period of time.
