no, most of those 中東國家女人唔介意咖.
I know a friend who is 中東國家人.
She tell me that some of those second wife is the wife's best friend.
If the wife think that her man is a good husband. Then, she will introduce her best friend to her husband and hope she can be the second wife and share his husband with her best friend.
Then, the 2 wifes/friends can live together, and can help each other take care of their family/kids.
