The christ leadership is the type a Christian man has to demonstrate in the church and home.

In the family, the husband should replicate such type of leadership so that even if his wife is an unbeliever she would be won without a word so, how much more a Christian wife?

Ephesians 5:25, 28-29 Husbands, love your wives, even as Christ also loved the church, and gave himself for it;

So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.

For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church:

A husband must cherish and nourish his wife giving her hope and joy,

Nourishment in this chase is not just about money but include emotional and metal nourishment.

A Christian husband is faithful, dependent,helps, listens and carry his wife along.

1 Peter 3:7
Likewise, ye husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.

A Christian husband should understand and honors his wife, as a weaker vessel, and acknowledged her as their also of the grace life.

Peter acknowledged this fact that men and women are not equal biologically, women are weaker vessel and some men know this, use this to their advantage but a Christian husband should not do this but should honor his wife, this will make her very confident both in herself and in the husband.

Romantic?
Should a Christian man be romantic towards his wife?
Yes, yes, yes,

The book of songs of Solomon is a whole book of love expression between a man and his spouse, but as a man you will have to understand wife's love language, which of course, should be in his courtship.
Lastly, A Christian husband should enjoy his marriage.
