After Reading Kate Chopin's The Story of an Hour

My first reaction to Mrs. Mallard's response to her husband's death news was that she's crazy. I mean how can she feel joy at her partner's death? That's outrageous! Then I tried to understand her why she'd felt that way. There must be a reason. Unfortunately the story lacks information for the readers. I, as one of the readers can only assume that maybe it was a forced marriage where she had to live with Mr. Mallard though she never loved him. Or he abused her at some point in their marriage. However we can only infer, can't conclude. Excluding assumptions aside, based on the text, Mrs. Mallard clearly felt grief about her husband's death. But what I don't understand is that her sadness instantly disappeared and turned into joy! Happy that she is free from her chains as a wife. I completelt agree to the fact the the dead ones become forgotten. No matter how much one loved them, as time goes on, living ones live and dead ones are buried in our hearts. That's normal! But Mrs. Mallard thought of joy and freedom on the day she heard of her husband's death! From that I can only conclude that she didn't love him truly.
