The topic of betrayal is so top and hot that I wanted to explore the other side of the coin. Namely, fidelity as a phenomenon that can be considered not only from the social side, but from the psychological, close to the biophysiological aspect. My respected colleague, Olga Kesler, responded to the proposed research topic. In our professional creativity, we have created articles about treason. A huge number of readers came to these articles in a short period of time. Which once again confirms the unpleasant feeling for me of the spiraling growth of acceptance of betrayal, all sorts of justification for its fact, presence in the life of official couples or at the beginning of a romantic relationship. A little reference to the spiritual component. in this topic - Sodom and Gomorrah is a hellish and inhumane place where people have lost their inner light, love, acceptance and purity from excesses and easy blessings. Do not think that I drown for puritanism or for the guillotine of any person who has betrayed him. But maintaining neutrality would be a veiled lie on my part. Therefore, I, as an individual, am on the side of fidelity. As a psychologist, I maintain neutrality in consultations, exploring his feelings with a person. The word fidelity itself was very popular during the long period of formation of our state. Love and fidelity were colored in a special sociopolitical context. And faithful people were cherished by fate itself. The image of a faithful hero illuminated with a ray the dullness that existed in many areas of human life. Loyalty, as a great emotional state, gives a person a lot. In addition to spiritual balance, of course, fidelity is one of the qualities of high and adequate self-esteem. In addition, fidelity is the sister of FAITH. When a person trusts himself, others, his partner and many other things in life. Basic trust in the world and loyalty go hand in hand and protect any person with a protective dome in moments of life's troubles or problems. Some readers may assume that this model of behavior is reminiscent of over-romanticization, but the tragedy associated with betrayal is an indicator that this particular model is more resourceful for a person. Thus, fidelity, as a psychophysiological character trait of a person, gives a person a long, healthy and balanced life. I invite you to dialogue on this topic, dear readers..
