The 'Codependency Model' was often used by therapists in the past when dealing with the sexual betrayal of their loved ones. Evolving research is starting to show that those who have suffered betrayal are actually suffering from trauma, which needs to be addressed appropriately to ensure effective therapy.

"After poring through the data, it has become clear to me that thousands of women and men are suffering deeply due to their partner's sexual behaviors outside of the relationship." ~Kevin Skinner, PhD

Post-betrayal, partners question their safety and worth in the relationship. They find it difficult to fulfill their roles, and as a result find themselves angry and avoidant towards their partner.
