God emphasizes the man loving his wife because that is where men often fail. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
Love never fails.
Only by the spirit of Christ can a man show this kind of love to his wife and be a good husband. And men need to be respected by their wives. God emphasizes this duty of a wife to respect her husband because it is easy, especially during times of conflict, for a wife to ridicule and belittle her husband. Men do so many foolish things that they are an easy target for disrespect. This doesn't mean a woman can't correct her husband when he makes a mistake, only that she should do so kindly, just as he should show kindness to her.
