(Sarah) Is it Love or Fear of Intimacy?

Lois Tyson puts a new spin on the "love stories" in The Great Gatsby. Personally, while reading the novel I did not associate the love interests to the fear of intimacy, however as Lois Tyson writes "think of each theroy as a new pair of eye-glasses through which certain elements of our world are brought into focus while others, of course, fade into the background." If we look at the novel through a psychoanalytical lense it makes sense that the characters have a fear of intimacy and that is what leads them to have dysfunctional relationships. So I completely agree with Lois Tyson that the characters are trying to be as distant as possible in their relationships, leading them to be unfaithful, lie, or in Gatsby's case be obbsessive. If the psychoanalytical lense revealed why the characters have dysfunctional relationships, is there any other insights this lense can give us about the characters, or does it end here?
