The days of being the sole provider have been gone for a long time. It is the year 2000 and no longer a man's world. So get a grip on that fragile male ego and bury it right now. In my opinion there is no room for ego in a loving relationship.
Money is one of the biggest causes of relationship failure today.
Tensions over finances can cause conflict in a loving relationship. This is especially true when the woman is the principal breadwinner in the family. The resentment felt by many men in this situation is one of the major contributing factors in divorce today. These feelings of resentment may lead to behaviors such as alcohol and substance abuse, physical and mental abuse, infidelity, and more. Of course, let us not forget the effect all of this has on children.
