Well, am questionning your justification as to why men and women act as u said. To a major extent, women care for religious and cultural values, and not just loosing on financial grounds so let’s say they may get/feel attracted to someone, they won’t express bcoz of values. Guys should do the same but they do it since they have nothing to loose on financial grounds, besides, they know she’s not gonna get a label of talaq and go back to her parents’ house, so they get by with some sorry.
By the way, here in United States, there’s a law called, “Alienation of Affection”. If a woman/man suspects that her husband/his wife is cheating or getting more affectionate towards another woman/man, she/he can file a case against the other woman/man of “Alienation of Affection”, which basically means that this other person who entered into their partner’s life has caused their partner to alienate their affection. I know one woman who hired a PI (private Investigator) to spy on her husband and recorded the proofs that he was getting more affectionate towards his female colleague. The woman threaten to sue the other woman. Her husband begged her not to do that, and agreed to sign over everything, house, cars, and other assets in his wife’s name and agreed to be loyal to her. So now if he cheats, he would be out on the streets since she has everything. lolllzz
There was a case not so long ago in North Carolina where the woman sued her husband’s lover and her husband got kicked out of the house, lost right to everything. His girlfriend was fined by the Court for a big sum of money 50K or 500K or perhaps more, not sure about the amount. There has been a movie on this too.
So ladies make sure you get married in one of those states which accept the law of Alienation of Affection, I bet even if he looses sight of religion and or other cultural and family values, he wudn’t wanna loose everything he built so far
