What reservations does nick have about gatsby's feelings for daisy

In F. Scott Fitzgerald's novel The Great Gatsby, Nick Carraway feels that Daisy and Gatsby's relation will most certainly end poorly. Nick believes that the couple's relationship is structured upon illusion, at least on the part of Gatsby. Nick believes that Gatsby is attempting, through his relationship with Daisy, to relive the past in order to create a new future. Furthermore, Nick feels that Daisy's affections for Gatsby is owed not to any sort of true, emotional love, but rather an attraction to his wealth.
