If we look at the novel The Great Gatsby written by F. Scott Fitzgerald from the lens of psychoanalytical theory we will see the fear of intimacy among all the characters of the novel. They all don't want real intimacy in their relationships because they fear abandonment, emotional pain and rejection from others.
Tom by spending his interest, time and energy between two women Daisy and Myrtle protects himself from real intimacy with either. Tom's relationships reveal his desire for ego gratification rather than emotional intimacy.
Daisy wants ego reinforcement by her relationship with Jay Gatsby. The fear of intimacy of Daisy and Tom is related to low self-esteem. Just as Tom uses Myrtle to avoid the emotional problems in his marriage, so Daisy uses Gatsby. Daisy's marriage has become painful and her affair with Gatsby provides a welcome distraction. She thinks about her affair with Gatsby as an appropriate punishment for Tom that's why her affair functions as a psychological defense. Nick and Jordan fear intimacy too. Myrtle, because of her economic desperation uses Tom Buchanan as a ticket out of George Wilson's garage. Gatsby believes that his ultimate goal is the possession of Daisy but Daisy has no desire for intimacy with Gatsby.
