For men, it is often a problem when it comes to expressing love. Understanding and patience is what we all need. Even if you make a million dollars, try to put efforts to spend time with her. That is very important if your relation is to be good.
Life is very short.
Do not stop loving your wife. Take time to know their problems. Tell your wife to offer whatever help possible. Remind your wife often as to how special she is. Re-assure her with words that you alone can know.
