I hate to generalise, because every family and every person in those families are different. Some men are great 'fixers', others find it difficult to make decisions. Some husbands do housework, others faint at the sight of blood. Some men are comfortable talking about emotions and their faith, and others are much more private. But some things are true for every family.
Husbands are the head of the family, their wives are the heart.
A head without a heart lacks compassion and finds it hard to love. A heart without a head lacks prudence and finds it hard to trust. Put together as head and heart, husbands and wives teach each other to trust and to love, lessons that they might not learn on their own. In addition, fathers have tremendous influence on the formation of their children. Faith may be taught by mothers, but it is passed down by fathers.
