Nick observes a tense conversation between Tom and Daisy in the kitchen, where Tom is openly flirting with another woman in front of Daisy. Daisy seems uncomfortable and unhappy, but doesn't confront Tom about his behavior. This scene highlights the strained relationship between Tom and Daisy, and hints at Tom's disrespect for Daisy.
When Myrtle says "Daisy, Daisy, Daisy! I'll say it whenever I want to! Daisy Dai-" Tom smacks her and breaks her nose. However, this only angers him when spoken by his mistress, so I am not completely sure this is what your looking for.
Tom's having an affair and Daisy knows it, while Daisy is seeing Gatsby.
Tom Buchanan says Daisy loved him when she married him and she loves him now on page 135 of "The Great Gatsby" by F. Scott Fitzgerald.
Gatsby says "In any case, it was just personal" about Tom and Daisy's marriage because he believes their relationship lacks the depth and purity of his own feelings for Daisy. Gatsby sees their marriage as shallow and materialistic, while he views his love for Daisy as genuine and profound. This statement reflects Gatsby's perception of his love for Daisy as more meaningful and significant than her marriage to Tom.
Nick's second cousin is Daisy who is married to Tom, used to date Gatsby who Nick lives next door to. Daisy and Tom are friends with Jordan who attends Gatsby's parties. Tom is having an affair with Myrtle who is married to Mr Wilson who kills Gatsby at the end because he ran over his wife but it was really Daisy.
Gatsby really disapproves of their relationship. He wants Daisy all to himself
