Does A Man Need A Women To Be Fulfilled in Life?

Society always tries to convince man on how important a women is in a mans life an how they help make a man. They will say silly rhetoric such as "behind every great man is a strong woman" " Happy wife is a happy life". If that is the case how is it we have men who are hermits, sages, monks, religious leaders who have made it to the end of  life without the need of woman companionship?
