Infidelity, actual or suspected, can trigger strong emotional reactions, such as jealousy, which could lead to the dissolution of the relationship. These reactions were predicted to vary with the severity of the infidelity, with the sex of the participant, with previous experience with unfaithful partners, and with the length of the relationship. We employed a sample of 447 Greek-speaking participants who were asked to indicate their reactions in different scenarios of infidelity. We found that more severe acts of infidelity were associated with higher emotional upset and jealousy and lower probability of forgiveness. Moreover, women indicated stronger emotional upset and jealousy than men, but they were more likely to forgive their partners. Furthermore, participants indicated more emotional upset and jealousy if they were in a long-term than in an early-stage relationship. Finally, participants who were older and who had experienced infidelity from their previous partners were more likely to forgive their partners’ infidelity than participants who were younger and who did not have such experience. Our results indicated that several factors determined the severityof the reactions to infidelity.

对不忠行为的反应和宽恕：探讨严重程度，人际关系长短，性别和以前的经历影响

实际或怀疑的不忠行为可能会引发强烈的情感反应，例如嫉妒，这可能导致关系破裂。预计这些反应会随着不忠行为的严重程度，参与者的性别，与不忠伴侣的过往经历以及关系的长短而变化。我们抽取了447名讲希腊语的参与者作为样本，要求他们指出他们在不同信仰背景下的反应。我们发现，更严重的不忠行为与更高的情绪不满和嫉妒以及较低的宽恕概率相关。此外，女性比男性表现出更强烈的情绪不满和嫉妒心，但她们更有可能原谅自己的伴侣。此外，与长期恋爱相比，与长期恋爱相比，参与者表现出更多的情绪不满和嫉妒心。最后，年龄较大且经历过前伴侣的不忠行为的参与者比年龄较小且没有此类经验的参与者更容易原谅伴侣的不忠行为。我们的结果表明，几个因素决定了对不忠行为的严重程度。
