where in the bible does it talk about women runing the house and men the affairs outside the house?

hmm lets see:

Titus 2:3-5 - The aged women likewise, that [they be] in behaviour as becometh holiness, not false accusers, not given to much wine, teachers of good things; That they may teach the young women to be sober, to love their husbands,

to love their children, [To be] discreet, chaste, KEEPERS AT HOME, good, obedient to their own

husbands, that the word of God be not blasphemed

1 Corinthians 7:39- A woman is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, but he must belong to the Lord

So Biblically speaking Christian women CANNOT divorce their husbands.

Throughout the New Testement it is written over and over again that women have to be obedient and submissive to their husbands:

Colossians 3:18- Wives, submit to your husbands, as is fitting in the Lord.

1 Timothy 2:11- A woman should learn in quietness and full submission.

1 Corinthians 11:3 "Now I want you to realize that the head of every man is Christ, and the head of the woman is man, and the head of Christ is God."

1 Corinthians 11:7 A man ought not to cover his head, since he is the image and glory of God; but the woman is the glory of man."

1 Peter 3:6- Just as Sarah obeyed Abraham, calling him lord, and you have become her children if you do what is right without being frightened by any fear.

Ephesians 5:24- Now as the church submits to Christ, so also wives should submit to their husbands in everything.

Ephesians 5:22-Wives, submit to your husbands as to the Lord.

Now as for men, this I believe answers your question on men working outside:

1 Timothy 5:8- But those who won't care for their relatives, especially those in their own household, have denied the true faith. Such people are worse than unbelievers.
