It is not right for a man to be alone

What does it mean that a wife is supposed to be a "helpmeet"?

In the Bible, it is written of Adam that “It is not good that the man should be alone; I will make him an help meet for him” (Genesis 2:18). In this instance, help meet means a help that is meet (proper) for Adam, and the term has since been transformed into helpmeet, or helpmate. 

Now, this expression does not translate into “A wife should be subservient to her husband” and fulfill his every wish and command. Rather, it is a recognition that men and women, as social creatures, require a mate to fulfill their needs for human contact and reproduction. Not only that, but they need each other to be complete in the sense that yin fulfills yang, and yang fulfills yin. That is, they are complementary.
