Men and women have different purpose, including in the relationship. It should provide for the family from the outside, that is, build a house and fill it with the necessary content, but rather to provide women with the opportunity to build this house. A woman has to provide for his family from the inside, that is, take care to make everyone happy, loved, build relationships with everyone.
And if He did not perform the duties (poorly built a house), this family will be unlucky externally (the house collapsed and fell asleep you the rubble, and it is necessary to build a new, and all this time to live somewhere, feeling perhaps considerable inconvenience). And if it is not properly performing their duties (bad builds relationships), this family is doomed (relations collapsed and showered debris, breaking heart, which is much more difficult to recover than any whatsoever house).
