Men, that are not faithful, tell women that they love them because it’s what they think that the woman wants to hear. Oddly enough in some cases, they are even genuine in what they are saying, they really do believe that they love her.
Apart from this, he has a problem which stems back to the days of the cave man, when man was the hunter and the conqueror and unfortunately it still remains in his inner most instinct to continue being dominant. Obviously, he no longer has to hunt for food any more, but he now hunts for women instead. Each woman that he wins over is a victory and a conquest for him, and most probably boosts his morale and his ego.
This sort of behavior has been going on for centuries with the man believing that it is perfectly acceptable for him to be unfaithful, so long as his wife does not find out. To give the male species a tiny bit of credit here, he will endeavor to do his utmost and ensure that his wife never gets to hear about his fling, including some more lying, if need be. He probably keeps in mind the line, “That what you don’t know can’t hurt you.”
Up until a few decades ago, women had to get used to this kind of treatment from their husbands. It was accepted because even the kings were doing it, and if you were wise you just kept quiet about it. In those days what were you going to do? Women did not work and had no other choice, and without a husband how would they live?
He the man, the husband, in most cases, does love his wife, but she is a separate issue and his fling is his fun and excitement. She is the mother of his children, she is to be respected, but she no longer gives him the thrill that a new conquest can give him. As the will power of men is not very strong and seems to be ruled more by another part of his body rather than his brain, he can easily fall into these types of temptation. It only needs another woman to show him that she is interested in him for him to fall right into the trap, as he really wouldn’t have the strength to resist this.
Having said all this, we cannot put all men into the same basket. There are some men out there who do know how to be faithful and have proved it to their wives to whom they have been married for over 50 years. At the end of the day, it all boils down to whether a man feels that he has to keep reminding and proving to himself that he is a man. There is a chance that he is just happy to be who he is and values the happiness of his wife more than his ego trips.
