In the movie Julie and Julia, Julie told Julia that she no longer liked her because she felt that she no longer loved her as much as before. Julie went through a painful period in the movie. She felt that she was hurt, but she also felt tired and distrustful of love because of her past experiences. All these factors combined made her no longer open her heart to Julia as she used to, and she no longer had deep feelings for Julia.
I'm not sure which specific 'Julie story' you are referring to. There could be many stories about someone named Julie. It could be about Julie's adventure in a new city, her relationship with friends or family, or her achievements in a particular field.
Julie of the Wolves is fictional. The author crafted the story using imagination and literary elements to engage readers and tell a compelling tale that isn't based on real events.
It has elements of truth. Julie Powell's blog and Julia Child's life form the basis, but creative liberties may have been taken to make it more engaging for the audience.
