It's unfortunate, but often behaviors that are strange originate in a person due to the cultural messages they were exposed to while growing up. Often a woman like you are describing doesn't know HOW to handle things herself because of how women are treated in their culture. Many of these women don't pick out their husbands and their marriages are arranged for them. There are class messages in that culture too where they are actually encourged to be entitled and expect others to do things for them. It's very possible her husband will take her son back to india and she will never see her son again unless she goes back to india herself. She may have no choice but to do so either because if her husband does abandon her she won't have anyone to support her. She is probably very frightened.
