And in Russia or in Ukraine... If the man has achieved something in his life - if he has good work, a house, a beauty-wife - he should have also a mistress. He is simply obliged, or in the eyes of his pals he is not a real man. But not all men are such monsters, there exist fair and decent husbands. But all the same, unfortunately, there are still a lot of dishonorable men. And Russian ladies are very unhappy with it.
Here, in the Western world, to have a mistress is simply not moral and not prestigious. It is a low status, a bottom of society. In the company a man won't start to brag that he slept with someone yesterday. Nobody will approve it, only condemn. Americans, Norwegians etc. value their family and the reputation. They love the wives and carry them on hands (help about the house, take care of children etc.). And if do not love them, then respect as a woman, as a wife, and as the mother of their children. Men think, that, being unfaithful to a wife, they act very badly, cause her great suffering. And nobody wants to hurt a close person. Many of them have photos of the wife and children on the worktable. And no businessman respecting himself will start spoil his glory for the sake of relationships on the side. Because his business can easily shake in that case as clients and partners will cease to respect him.
There are, certainly, some men here who are unfaithful to their wives. But, there are few, and the majority of them are losers, people who couldn't find their niche in society. But in comparison with Russia and Ukraine there are few of such men. And here the man is unfaithful only in the event of bad relations with the wife, when something is going wrong, but not for the sake of an entertainment.
And it is no surprise, that foreign men consider Russian ladies jealous. It, probably, because we got used so to unfaithfulness so much, that somewhere at a subconscious level, not knowing that, we are constantly afraid: what if he is unfaithful to me?? But he is not going to be unfaithful to us, no. If everything is all right in relationships, if everything is fine at home, with the family, he won't be unfaithful. Just the mentality is such.
