Genesis 2:18"And the LORD God said, “It is not good that man should be alone; I will make him a helper comparable to him.”
This is the first mention of God saying something wasnt good. Its not a good situation men are alone. Some may manage better than others. Gods purpose, I believe, was to make him aware of his need for a wife. She was to be his help meet. Not below him to walk on. Not above him to lead him. But from his side to come alongside and complete him. Men will not be completed without his wife. You may work single, but the ability to be complete comes with your wife. This is that the couple walks in Gods direction.
