Well obviously! I never really liked you anyways...
Daisy vs. Self
I don't know who to choose...Tom or Gatsby? I love them both, but I can only have social importance with Tom! Jay is new money... I can't decide...
Tom vs. Gatsby
You think she'll leave ME for some nobody? You have no status!
Daisy loves me!
She has loved me ever since we met in Louisville! We'll be married and start a life of our own, like you never existed!
After Gatsby's death, Nick calls up Jordan to put an end to their summer romance. He breaks up their relationship, and Jordan tells Nick that she was just using him for a fun summer and would have never stayed with someone with such a low social status anyways. Nick is hurt he broke off the little love he had for her, but knows it is ultimately for the best.
After Nick has introduced Gatsby and Daisy again, Daisy is conflicted whether she should stay with her daughter and husband, Tom, or leave them to be with her one true love, Gatsby. Either way, she would have wealth, but with Gatsby she would be "new money", and would not matter in social society, like she does with Tom as "old money". To Daisy, her image is more important than her feelings.
When Tom, Daisy, Gatsby, Nick, and Jordan are in the Plaza Hotel, Gatsby tells Tom of his affair with Daisy. He proceeds to tell Tom of their plan for Daisy to leave Tom, but Daisy loses confidence in the plan quickly, and Tom's confidence that Daisy will not go anywhere is reassured. Tom and Jay continue to argue over whom Daisy will choose, and Jay Gatsby ends up losing the fight and Daisy.
