I came to cry my wife’s friend and somehow I slept with her by chance

Johnny cannot come to terms with the fact that his wife pays a lot of attention to her friend. He was overwhelmed with jealousy and the guy cannot find a place for himself. What if she cheats on him right behind him? Bad thoughts do not go out of this head, because he came to cry his wife’s girlfriend in the hope of explaining the situation for himself. My wife’s friend began to calm the poor guy and tell him what he wanted to hear. I asked him to calm down, but the guy could not stop. He almost burst into tears and at the time of moral suppression, his wife's friend kissed him to calm him down. He liked such a step, he succumbed to passion and somehow accidentally slept with her. Now the guy should become easier, because if she changed, then he already avenged his wife with an advance.
