Research has found that men hold more positive attitudes towards their female ex-partners than women do towards their male ex-partners.
This has been revealed in research done under the research document: Sexual Strategies Theory: An evolutionary perspective on human mating.
Gender-related variables
Gender-related factors determine ex-partner attitudes, thereby determining how a given sex looks back on their past relationships after a breakup.
Research has revealed that women have stronger feelings of attachment or love to an ex-partner than men do and are said to more connected to a past relationship.
