Incurable disease?
Yes it is. No one wants to believe in it but it is so. The psychologists do their best in order to find a way to deal with this problem but there is nothing they can do. There are a number of psychologists who state that they sometimes even refuse to try to heal one who suffers with jealousy. There is no way to do that as it is impossible to detect the reasons for jealousy. There are cases known when a man is jealous for his wife who were sitting at home caring about their one-year-old child. I bet it is needless to say that such a woman simply has no time to cheat her husband even if she wants to.
You are the one who is able to realize it, I am the one who is able to realize it but her husband is the one who will never realize it. The obvious things can't be explained for him and so it is impossible to cure him. The psychotherapy is based on explanation of some things that are based on the common knowledge of a person. But the one who is jealous is simply not able to realize the most common things. He is ready to believe in everything except in his wife's inability to cheat him. No one knows why it is so. Psychologists tried to mark out personalities inclined for jealousy but these efforts gave no results.
So jealousy is an incurable disease. It is okay if the jealousy of a person you are in love with ends with common where-have-you-been questions or something like that. But, there are such kinds of jealousy that never ends with these questions and usually developed in mania. And that mania can't be healed; there is no way to assure the one who is jealous that he or she has nothing to be afraid of. They will always manage to find proofs for their suspicions, they will always hear the tone of lie in one's voice and they will always think that three minutes it is enough for cheating.
The rational part of a mind simply doesn't work when the brain of a person is occupied with jealousy. There are two kinds of people able to believe in miracles and fantastic things. Theses groups are children and people who are jealous. It is easier for them to believe that a person they are in love with cheats them twice a minute than to believe that a person is in love with him or her and will never hurt him or her. No matter how the wives and husbands try, no matter how hard the psychologists try it is impossible to cure a heart poisoned with jealousy.
The only possible way is to suggest for a person the real fact of cheating. There are cases known when people were cured by means of replacing their fantasies about cheatings with consolidation of these thoughts. And the anxious of a person were replaced with depression. The depression is gone in some days and a person becomes able to live happily and forget about his or her jealousy. Though, this method is not common and there are people who will only grow madder than they were before. So, if you want to deal with a jealousy on your own you'd better don't use this method.
