What does Jordan's story of Daisy's marriage reveal about Daisy?

Jordan's story paints a pretty unflattering picture of Daisy. We find out that Daisy was drunk at her bridal dinner and denying that she ever wanted to marry Tom at all. She is clutching a letter from Gatsby (this is implied) and falling apart over her impending wedding to Tom. Daisy however pulls herself together. She marries Tom the next day fully aware that her social and economic status will always be among the filthy rich. Daisy sacrificed her "love" for Gatsby to be a true socialite. Somehow that doesn't sound very romantic!
