what do things does she reveal in her conversation? What situations from her past does she reveal?

Curley's wife is clearly starved for conversation and launches into a reprise of her discontented story of what might have been. She reveals her desire to be an actress, and that someone told her he could get her into the movies. She waited for the men to write, and when a letter didn't come, she accused her mother of destroying it. Then, she claimed she married Curley to spite her mother..... to get away.
