You shouldn't attend your ex's wedding. The advantages of attending an ex-wedding are dispensable, but the disadvantages are inevitable and serious. First of all, for myself, it is very likely to bring psychological burden to myself at the moment of witnessing the other party's wedding. From the perspective of developmental psychology, Arthur Aron, a famous psychologist, once established a "self-expansion model". In this model, two people in a love relationship are like nested rings, absorbing many characteristics and personalities of the other party and gradually merging into a whole. When this relationship broke up, a part of me left with it. And at the moment of witnessing your ex enter the wedding hall, a part of yourself that you have lost will invade your heart again and bring you pain. I chose not to attend my ex's wedding because I didn't want to experience the pain of leaving myself again. Secondly, for the other half of the ex, your appearance may bring him unnecessary trouble. Empathy, now from the perspective of the ex-spouse, in the sacred and warm hall of the wedding, the appearance of a person who has countless memories with your spouse will inevitably bring a strange feeling, but how many people are confident that they can completely avoid this feeling? Imagine that when you are wearing a white wedding dress, holding flowers and listening to his lifelong promise to you, the picture that comes to your mind is that he is kissing another woman, and that person appears in front of you today. This is really a sad story. What's more, in reality, there are many shocking examples of predecessors ruining the wedding scene. If you don't attend the wedding, these unstable risks and unnecessary troubles can be avoided. Why not? Finally, for you and your former friends, your appearance may cause them to talk and create an embarrassing atmosphere. According to Erica, an American social psychologist, a romantic relationship will make both parties share the same friends and activities, and then form a circle of friends within a certain range. The breakdown of the relationship between two people and the subsequent collision will affect the nerves of most people in this circle of friends. The universal psychology of human curiosity will make them have unpredictable guesses about you at the wedding, and there will be sympathy, gossip, banter and other psychology. If I don't go to the wedding, I don't want to face this discussion and embarrassment. I chose to attend my ex's wedding, mostly because I wanted to send my sincere wishes to the lovers who had promised each other, or to completely seal up the feelings that had left a deep impression in my heart, bid farewell to the past and let go of the past. Because of this, in the most sacred event of the other party's wedding, considering that his attendance will bring many inevitable and even serious disadvantages, he will not attend his predecessor's wedding, because not disturbing is the best blessing for them. In short, if you still have a good impression on your ex, you don't have to go.
