This is especially true if the woman in the relationship makes more money than the man.
The Need to Provide All men have an inherent desire to provide for the ones they love.
A woman wants to be cherished; she does not want your paycheck.
If you are in this situation try to realize that you have a few choices here.
You can either strive to get a better paying job and improve your income or you can resign yourself to the fact that she makes more money and get on with your relationship.
