The polygamy is by nature peculiar to men. It is shown in the need to have relations with several women, and the man can love one lady, but will have communication with another.
Even the most respectable men, having strong family, happy marriage and even children can be changed the soulmates, and business even not in lack of love for the spouse. Actually the first reason of similar behavior is in substitution of requirements. People can have the certain need which is expressed in aspiration to self-improvement, career development and vital success. If the man tests dissatisfaction in working affairs, he will think that people do not perceive it seriously, and the wife does not respect any more. To receive though some recognition in society, he tries to ego-trip at the expense of other woman though he can love at the same time the soulmate.
The second reason of unconscious treason to the mistress - a lack of parental love of the childhood. If parents did not indulge your husband attention, he did not know caress and tenderness, at more adult age it will lack attention only from one woman. He will become the artful temper, in search of love and heat from various girls. And will always seem to it that surrounding ladies give it not enough love.
The third reason of matrimonial treachery from the loving man is at his age. Not for nothing people tell such phrase as "a gray hair in the head, a demon in an edge". With achievement of forty-year age some men begin is aggravated to feel approach of an old age, and they so want to try all vital temptations which they were not able to afford in youth. The first what men of such age - an extramarital affair usually decide on. Men try to make up in all ways for lost time, without wasting time. The most interesting that to them women with whom they sleep are not important at all. To them process and understanding that they are capable to tempt great ladies is important.
The fourth reason is even not in the man, and in his spouse. The fact is that women begin to grow cold to the partner with age, the intimate proximity does not want to them. They too strongly are tired of household chores, household problems and of education of children. With approach of evening of the wife in exhaustion go to bed, ignoring needs of the husband. Men, unfortunately, remain nothing else how to make matrimonial treachery though actually they have tender feelings of love for the wife.
