In the book The Great Gatsby is there a quote that shows that Daisy doesn’t care about Gatsby?

Toward the end of chapter 7, Tom confronts Gatsby about his true identity and reveals to the entire group that Jay Gatsby is a bootlegger. Daisy is shocked at this discovery and immediately abandons all hope of possibly leaving Tom for Gatsby to begin a new life. While Daisy does not directly tell Gatsby that she no longer cares about him, her actions indicate that she has moved past the possibility of sharing a future with him. Daisy becomes quiet and steadily backs away from Jay Gatsby after Tom reveals his true identity. After Daisy accidentally kills Myrtle Wilson while she is driving Gatsby's car, she tells him to wait outside and make sure Tom does not harm her. When Nick arrives at the Buchanan home, he spots Gatsby hiding in the bushes. Gatsby then explains why he is hiding in the bushes and is clearly concerned about Daisy's well-being. However, Nick looks into the window and sees Tom and Daisy amiably having a conversation. Nick writes,

They weren’t happy, and neither of them had touched the chicken or the ale—and yet they weren’t unhappy either. There was an unmistakable air of natural intimacy about the picture, and anybody would have said that they were conspiring together (Fitzgerald, 83).

The fact that Daisy is composed and comfortable around Tom and the fact that she is not concerned about Jay Gatsby reveals that she does not care about Jay Gatsby anymore. Daisy does not feel bad or even consider the fact that Jay is still waiting outside in the bushes for her. Her lack of empathy and compassion for Jay Gatsby indicates that she does not care about him at all.

Perhaps the best evidence to prove that Daisy doesn’t care about Gatsby as much as she claims to care about him comes in the middle of Chapter 7. When Nick, Jordan, Tom, Gatsby, and Daisy go into the city, and Gatsby announces that he and Daisy are in love, Tom begins explaining that he knows Gatsby gained his wealth through illegal means. Gatsby tries denying everything, but Daisy 

was drawing further and further into herself, so he gave that up, and only the dead dream fought on as the afternoon slipped away, trying to touch what was no longer tangible, struggling unhappily, undespairingly, toward that lost voice across the room.

Here is the definite proof that Daisy will not choose Gatsby over Tom. The dream of being together is now dead and Daisy is something that is “lost” and “no longer tangible.” It seems relevant that it is the realization that Gatsby made his money in unscrupulous ways (and thus is viewed as lower class) that ultimately turns Daisy away from him. She never quite cared about Gatsby himself but rather the wealth and class he represented, and when that was stripped away, she lost interest.
