In "Of Mice and Men", what is the reason that Curley's wife's dreams were destroyed?

A great deal of Curley's wife's characterization comes from her actions, dialogue with the other characters, and what other characters think of her. Until the end of the book, the reader is only able to see Curley as a "tart," or morally loose woman. It appears as though a great deal of her dreams have been repressed by the men in her life. It is not until Curley's wife speaks to Lennie in the barn towards the end of the novel that we realize she wanted to be an actress, and, because of her mother, she was unable to pursue this dream. Since her mother would not allow her to become an actress, she runs off with Curley, which begins a life steeped in loneliness and regret.
