I can't figure out if Nick has real feelings for Jordan or if he just wants to date a girl whom he admires in The Great Gatsby; which is it?
Jordan Baker certainly intrigues Nick Carraway. As an "innocent" from the Midwest, Nick is unused to meeting worldy-wise females such as Jordan. When he first sees her at Daisy's house, he becomes fascinated with her voice and her cool manner (the stereotypical "hard-to-get" appeal). Later, though, as Nick learns more about New York's Old and New Money society, he realizes how "incurably dishonest" Jordan is. He notes that she lies on several occasions, cheats at golf, and drives recklessly.
At the novel's end, Nick seems to possess sympathy for Jordan and guilt regarding his distancing himself from her after Gatsby's death. My take has always been that Nick did not intentionally use Jordan and then "drop" her as she claims. Rather, I think he was caught up in the idea of her and then found her and her crowd repulsive when he realized that she was not much different from Tom and Daisy who smash up people's lives and then retreat into their "cocoon of wealth."
