its not that hard.

First of all god put a woman here to complement man.

A man must respect his wife and in return a woman must have deep respect for her husband gods words, words to live by.

Than we need love, and shown not just felt.

Kindness shown.

Help with the house and kids dont leave it to us.

A nice night once a month without kids (this may have saves my marrige)

the list goes on and on but some of the most  important. But it all starts with respect.
