ELI5: Why does Frodo leave the Shire at the ending of the Return of the King?
gpt
Wearing the ring changed Frodo. He can never be truly happy (not in the way we would understand at least) and seeing everything he used to love causes him a lot of pain. Also, note that he leaves Middle-earth, not just the Shire. He is trying to get as far away from any reminders of his life.
