I do not agree with your view about that woman,if a woman does that she is not worth to be called a woman and thats how women think and she does not respect the marriage institution as a general rule a woman should know and also a man who are married that they should not flatter or do something that if the other patner knows might bring trust issues.Especially for the woman because i know that she is the one who holds the family together,if things are to go wrong the woman is the one who is judged hashly by the community,every man knows that a woman will always be teased but always trusts her and also her,problem of infidelity is just a symptom of an underlying issues that are left unattended way before even they got married.marrying a beatiful woman is not an issue the issue is if she has a beatiful heart.woe unto you if you fight tooth and nail to impress a beatiful lady for marriage just because she is beatiful when all is gone and she was there because of wealth you will see true colours.so if a lady has issues with his man he should face the man and also best is to get a person that who will not side to hear part of the story.the nature of women in to protect their marriage and unless he married an idiot things can be sorted out and if she wants to sleep with another man let her do it after they have separated officially but to do it in marriage and the man knows then hell rains and thats where physical assault starts and it becomes crime of passion
