Individuals in dating and marital relationships experience various transgressions that require forgiveness (e.g., hurtful communication, mistrust, lies, or infidelity). This study examines forgiveness-granting strategies in the context of forgiveness tendency, relationship length, commitment, satisfaction, and relational consequences to better understand relationship dynamics. 649 individuals (532 dating, 117 married), aged 18–65 (M = 26.00, SD = 8.82) participated. The sample included 517 women (79.7 %) and 132 men (20.3 %). Participants described a forgiven transgression and completed questionnaires, including the Multidimensional Forgiveness-Granting Scale (MFGS), Transgression-Related Interpersonal Motivations Inventory (TRIM-18), Relationship Assessment Scale (RAS), and the commitment subscale from the Investment Model Scale. One open-ended question (types of forgiven transgressions) was analyzed consensually. Quantitative data were analyzed using correlational analysis, regression analysis, and t-tests. The most common transgression was infidelity. A linear regression analysis showed that the strongest positive predictor of relationship satisfaction was the tendency to forgive one’s partner. Nonverbal displays positively predicted relationship strengthening, while the discussion strategy predicted relationship deterioration negatively. These findings emphasize the importance of how forgiveness is communicated and may inform interventions to enhance romantic relationships.
