The meeting between Gatsby and Daisy in the party was very awkward. It was too long ago since Gatsby saw Daisy, so he do not know how and what to act every time she's around.
Because of their difference in the status of life (Gatsby's poor and Daisy was rich), Gatsby still considered Daisy as old money (famous and rich). He was obsessed of winning Daisy back because he is falling her all over again, and that he knew that Daisy never loved Tom. His concern for Daisy is that, Daisy wants to have freedom, however she believed that Gatsby could not support their relationship their whole life.
At the party, Gatsby wants to impress her but Daisy was not impressed since the party was reflecting on the present day which she do not want to live in. She do not want to take responsibility in her whole life. Thus, the party that Gatsby thrown out was not valid.
