A one sided relationship is an extremely difficult thing to deal with. When you feel you are the only one putting any effort into the marriage, you begin to resent the costs in all areas and it becomes a very difficult thing to maintain. 

A man will spend his last dime on a woman who appreciates and needs him. He'll fetch her the moon if he can find a tall enough ladder. Neither does it become a drudgery. It's why women sometimes wake up to find another woman has stepped up and filled in the gaps and they become indignant at what they created themselves. I do not approve of such behavior but it still happens. 

My pastor used to say, "A man doesn't run away from happiness."
