This situation can occur unconsciously. The transition to a new stage of relations requires a certain crisis situation. For some, such a situation becomes treason, which, in the opinion of one of the partners can liven up the relationship, or to put them a point.
The desire to define themselves
Even in a happy marriage one of the spouses may have doubts that it lives as once wanted. If the answer is positive, then the hazards relationship is not, but in case of negative answer can begin the search of new sensations, including a new sexual partner.
There are times when infidelity occur spontaneously. This may be to blame alcohol, a certain emotional state, leading to an error, fix that will be difficult.
Women's and men's infidelity is often caused by the appearance in the child's family. The man explains treason because the wife is not giving him time, not taking care of himself, gaining weight. The woman on change can push the output of the decree. Isolation ended, the woman appears again in the society, and here it is waiting for fresh emotions, and with them having an affair.
The thirst for experience
Early marriage, lack of sexual partners before the relationship can cause one of the partners begins to feel that he could get more of a variety of emotions and feelings, if he had more partners. And the first love passes, and the couple begin to see that life is not just limited to relationships. As a rule, cheating in this case ends with the dissolution of the relationship.
The lack of attention, rudeness, cheating often mean that the offended partner is cheating trying to get revenge for inflicted wrongs.
In the absence of a full and varied sex life in marriage starts to make sense (sometimes deceptive) that the other person will be better. Situation is often a dead end – it is better from infidelity did not, the feeling was the same, but the relationship after the affair at risk.
Attempt to verify the femininity or masculinity
Sometimes sex life cools down, the man ceases to feel confident, and the woman is desirable. To prove yourself the opposite, one of the partners (and sometimes both) tries to return confidence with another partner.
