In Chapter 7 Why Does Gatsby Stop Giving Parties?

In The Great Gatsby, Jay Gatsby throws lavish parties attended by people who are basically strangers to him. He wants to impress Daisy with his wealth and he hopes she will attend one of his parties. When she never shows up he employs the assistance of Nick, who is Daisy’s cousin.
In Chapter 7 of the novel, Gatsby stops giving parties because of Daisy's reaction to the party she attends and because he has attained what he had hoped – her attention.
Preoccupied by his love for Daisy, Gatsby calls off his parties, which were primarily a means to lure Daisy. He also fires his servants to prevent gossip and replaces them with shady individuals connected to Meyer Wolfsheim. Gatsby explains that this is because Daisy comes over every afternoon to continue their affair — he needs them to be discreet.
Chapter 7 marks the climax of The Great Gatsby. Twice as long as every other chapter, it first ratchets up the tension of the Gatsby-Daisy-Tom triangle to a breaking point in a claustrophobic scene at the Plaza Hotel, and then ends with the grizzly gut punch of Myrtle’s death.
