This comparative analysis is based on Nelly Alards novel Moment d’un couple from 2013 and its source of inspiration being La femme rompue of Simone de Beauvoir. These novels do both demonstrate marriage as a constitution and what happens to it when an infidelity takes place. This is thus a feminist analysis of the reaction and presentation of the betrayed woman and her way of coping with this new found situation she founds herself in. Alards narrative voice makes continuous reference to beauvoirian feminism. Beauvoir’s féminist theory is hence essential for this study as well as our source for theoretical framework as we aim to conduct an analysis using her elaborated terminology as a pivotal factor. Her conception of « The Other » is central for feminist theory as it focuses on the given female role in a patriarchal society. It is hence of relevance that Beauvoir published a novel by which that of Alard is said to be inspired. Whereas Beauvoir presents a character who herself normalises infidelity, and finds herself in second place, Alard presents a modern and more independent character. The crucial contrast is presented through Beauvoir’s normalisation of infidelity and Alard’s normalisation of violence against women.
