This question almost 'kills' billions of people on earth. Many men are in a painful place and make them unable to move after marriage. The conflict between his wife and his mother, how men should take this attitude. It is the male intent here that human maturity is tested and thought out when this problem arises.
As a man close to the mother, he will tend to protect her mother. Instinct based on teenage childhood experience is not entirely wrong. It is possible that the wife will be jealous. You can not protect it. Men who do not put a face in front of their wives are often considered cowards, against parents, afraid to be ungodly, this is when a man feels guilty about who to keep. Without us knowing how this problem is over, we have to deal with a cool head and give good instruction.
