It is striking that Elliot desires women, and is jealous of the other males for having female attention but never seems to have done anything ative to try to attract women. Did he ever ask a girl for a date? Most boys learn this, and will not be put off by inial lack of success: they will try repeatedly. Elliot gives up, and assumes that life is treating him unfairly by not providing for his emotional needs.
His behavior is clearly infantile. He has desires, but will do nothing practical to attain what he wants, much less to consider and purposeful action to make himself attractive to others. Wlliot was an infantile personality, seeking for his needs to be provided. He is a perfect representative of many 21st Century Americans. Someone else must provide: that is an infants world-view.
The first formative crisis in his life was his parents divorce. This cannot be underestimated. It took away his psychic support, and left him stuck in an infantile stage, with the infants attitude: Take care of me!
The anger he demonstrated is also typically infantile. It is characteristic, for small children are not sweet and cuddly all the time. It is normal for even babies to show rage, but fortunately they are too weak to act fully on their emotions.
Of course, bear in mind that I am not a psychiatrist, and dont even the play the part on TV.
