The transgression of the agreements between the couple is a current problem that generates discomfort on a personal, family and social level. In this article, an investigation is reported that analyzes a model that proposes the interaction between the variables positive cognition, positive affect and resilience as predictive factors that contribute to the understanding of the process of forgiveness of a transgression in the couple. 203 adults (103 women 60%, 88 men 40%) between 18 and 26 years of age participated in the research (Mage = 20.4, SD = 1.68). The hypothesized model was tested through the process of structural equations, finding adequate levels of goodness of fit x2 = 113.87, GL = 84, p = .02, SRMR = .05, RMSEA = .04 (.03 – .06), CFI = .97. The results found contribute to two essential levels in the line of investigation of the interaction between couples, firstly, at a theoretical level, it is provided with an innovative theory that allows us to understand the process of forgiveness in the couple and, secondly, to clinical level, for psychotherapeutic intervention in variables such as cognition and positive affect that would benefit a couple to overcome a conflict and reach a forgiveness.
