How did Gatsby prove to Nick his stories were true?

Gatsby showed Nick physical evidence and introduced him to people who could confirm his tales.

Gatsby finally tells Nick the truth of his life - how he came from a poor background, fell in love with Daisy, and did everything possible to become wealthy and be worthy of her. It's a tale of hope, love, and deception.

If you like the plot of the protagonist entering a dream to prove his Dao, then I strongly recommend "Primordial: Proving Dao in a Dream, Awakening is the Great Dao!" And "Stealing Dreams to Become Immortals" are for you. These two novels were both Xianxia and Xiuzhen novels, and they both had plots similar to entering a dream to prove one's Dao and learning martial arts. "Desolation: Proving the Dao in a Dream, Awakening to the Great Dao!" It was also related to the relationship between the protagonist and the Primordial World, and it was more characteristic of the character's emotions and delicate atmosphere. I hope you like this fairy's recommendation. Muah ~😗

Nick has a complex perception of Gatsby. At first, he's intrigued and impressed, but as the story progresses, he sees the flaws and tragedy behind Gatsby's facade.

Nick initially views Gatsby with curiosity and awe. As the story progresses, his perception becomes more complex and conflicted.

Nick's narration in The Great Gatsby is quite introspective. He shares his thoughts and feelings about the people and situations, providing a detailed and personal perspective. Also, he often reflects on the meaning and implications of what he witnesses.

Details about exactly how Nick Vujicic met his wife Kanae Miyahara might not be fully public, but it was probably a normal yet special moment. It could have been at a social gathering or through connections within their community. What matters is that they met and their relationship developed into a loving and committed marriage.

Nick changes quite a bit. At first, he's kind of naive and impressed by the rich lifestyle. But as the story progresses, he sees the hollowness and corruption beneath the surface and becomes more cynical and insightful.

Nick could doubt Gatsby's stories because they seem too fantastical or don't quite add up. Maybe Gatsby's manner of telling them raises doubts too.

It's possible that Nick telling the story was his way of making sense of what he experienced and trying to understand the complex relationships and motivations of those around him.
