When a third party appears in a relationship, it always causes pain to the deceived partner.
However, it is worth understanding that in a happy and harmonious family there is no place for a third person.
If it appears, then "fertile soil" has been prepared for it.
Not all men are able to tolerate constant refusal of physical intimacy. The intimate side of the relationship is important for them.
If a woman for some reason refuses to enter into an intimate relationship, then the man has a permanent partner on the side.
If before starting a family a man was not against having fun with other girls, then you should not expect that after marriage he will give it up.
Experts note that some men cheat because they do not know about another model of relationships. If you are ready, you can try to work with a psychologist to save the family. It is quite possible that this situation will change after working with specialists.
If you are in a long-term relationship, you need to take care of it. Not everyone can stay with each other for many years without cheating.
Therefore, try to make the relationship bring joy and pleasure. If marriage becomes just a habit, then the man gets tired of such a relationship. Therefore, the partner may look for a "breath of fresh air" on the side.
Some women ignore their man, focusing on children, work, and housework. This, of course, does not justify the representatives of the stronger sex, but it is worth understanding that this can become a reason for betrayal.
Therefore, it is important to give a man the proper level of care, love and understanding.
