What ruins doolitle life in Pygmalion?

In "Pygmalion" by George Bernard Shaw, Eliza's transformation from a flower girl to a "lady" introduces her to a new way of life that ultimately changes her identity and challenges her independence. While she gains the respect and admiration of others, this transformation also poses a threat to her sense of self and freedom as she grApples with her new social status and relationships. The pressure to conform to societal expectations and the loss of her former identity as a working-class woman create tension and inner conflict in Eliza's life.
