Gallimard is a weak man who has failed at several important ventures in life. Gallimard is awkward and unsuccessful in the realm of dating. He refers to his friend Marc who is a "ladies man" and laments that he cannot be more like his friend. Although Gallimard is married to Helga, their relationship is one of practicality. Gallimard does have one affair with Renee; however, she is sexually free and simply wants to have a sexual experience rather than any type of relationship with Gallimard.
In addition, Gallimard is insecure, and his insecurities are revealed when he assumes a domineering role over Song. He is so happy that he has a relationship with his vision of the ideal woman, and he revels in her submissive nature. Gallimard's past trouble with women is now over, and his insecurity translates into being cruel to Song.
Finally, Gallimard is naive. He believes in Song as the ideal woman when "she" is really a male government spy. Gallimard allows himself to be swept up in Song's stereotypical behavior, and this ultimately leads to his downfall.
