A person can respond to what is happening outside in a certain way only with what (that role or his part) is already in him. That is, the husband whom his wife deceives will be exactly that a man who in childhood played the role of a savior for his mother, to whom she “drained” her sorrows on the child’s father - her husband, when he was rude to her. Thus, the boy took on the role of a substitute figure - a “good husband” and partner for his mother, and in connection with this automatically turned into a rival of his father in their relationship with his mother. This is an inevitable consequence of the role played. Therefore, as an adult, a man will find/create for himself just such a triple relationship. The trouble is that in such a relationship - the relationship between parents - he will never become an equal partner. After all, in childhood he is only a child who has actually taken on an unbearable and alien role, and, moreover, unconsciously, forcedly. Therefore, the boy will learn this role only in this capacity - a weak and kind rival, doomed to defeat: due to his age and inability to really resist his father. Moreover, he will not do this in his parents’ family, because the true psychological subtext of the role is hidden from all participants in the script. The psyche of such a boy, already at the age of an adult man, will strive to react to the script given in childhood in order to take a different position. Therefore, in adult life, he will find himself in love triangles in order to change his position - in order to turn from a weak partner into a strong one. As long as he strives to win such a “duel,” he will enter into relationships with women who will cheat on him, or he will provoke them to cheat, or he will act as a “third wheel” = lover of someone else’s wife. For to completely solve the problem, the task is not to change partners and not to win “fights”, but to become aware of your role and all its components. It is also very important to see the entire “scenario”: in order to completely get out of the role you are playing, and therefore change the nature of your behavior in relationships with women. For example, stop mistrust and suspicion, then there will be no provocation of a woman to cheat. After all, a woman begins to cheat with such a partner precisely because she gets tired of being constantly accused of something she didn’t do. A paradox arises - a woman wants to prove that she is not a traitor. However, when you want to prove, she has already mentally also taken on this role, otherwise why would she prove that she is not what she is accused of? This is called projective identification. Further, leaving the role of the “third wheel” in a scenario with betrayal, a man needs to stop deliberately considering himself (and being) weaker in relation to other representatives of his sex. Show up, and not suffer in silence - talk about yourself, your needs, discuss relationships with a woman. Act. Be. And not just be present in the life of your partner. In general, you need to “dismantle” the previous role into bricks and replace those that form the building called the “love triangle” in the area of ​​your own participation in it. The same applies to women whose husbands cheat on them or who cheat on themselves. Or those women who become mistresses of married men. Each of them plays only the role and in the capacity in which she was assumed in childhood as a substitute figure in the bad relationship between her parents. Unfortunately, Until the role is realized, it will not be possible to get out of it. But it is not realized because it was imposed in childhood, and because it can be painful and scary to realize the quality of one’s adult participation in a bad relationship between parents. Moreover, realizing who he has become in a love triangle, a person usually experiences anger and despair , which are much easier and more understandable to pour out on a current relationship partner who has not lived up to expectations. Although in reality it will be anger at one of the parents who dragged the child into.
