I think Gatsby's American dream was to be rich and be with the love of his life, Daisy. I don't think his dream was ever accomplished the way he wanted it to be. The reason I believe this is because he only did the parties in order to be able to see Daisy; he got rich to give Daisy what she wanted. Gatsby wanted Daisy to leave her husband and go back with him, but that didn't happened she left him with all the problems. He died without his family and without the girl he loved next to him. He didn't accomplish anything.
