It's gives a command here; so apparently it's more than emotion and related to responsibilities/tasks/action. We can't control the first, but we can the latter. In Ephesians 5:22-29 Paul enumerates some aspects of that love: sacrifice, sanctification, cleansing, feeding, (bodily) care. All things hopefully done automatically when the well-being of the wife is on the husband's mind. Peter mentions 'giving honour to his wife as the weaker vessel' (1 Peter 3:7).
I don't think the knight-queen analogy from
@Daniel9v9 is helpful here - although the idea of protection is good and understandable; a knight normally was subordinate to both the King or Queen. The word 'knight' in old English literally means 'servant'. A husband is not a servant of his wife, it's the other way around. The NT does not call a husband to serve his wife, but it does call a wife to be in submission to/respect/obey her husband. Patriarchy is part of the NT instructions - it's not symmetrical. Just as the relationship between Jesus and a believer is not symmetrical; Jesus is our master / lord / king - He is in charge - we are His subject / subordinate / slave (a common metaphor used by Paul in his letters).
That is a highly inconvenient and uncomfortable pattern for Western society in the 21st century, yet quite explicitly present in the NT. Since about 30 years there exists a strong movement of egalitarian theology for which one of the arguments is that the 'rule' of man over woman is part of the curse of sin from the Fall, and that since for believers in the Kingdom the curse would be lifted, the presumed egalitarian situation of Adam & Eve in paradise should be restored by and between believing couples. The instructions and arguments from Paul and Peter however are incompatible with that position IMHO - I do not find the egalitarian viewpoint credible - it requires a very forced reading of the NT.
Jesus loves and cares for me, yet still He is my master / lord / king who I have to submit to, respect and obey. The same pattern applies to a husband and wife.
Btw personally I'm not the golden standard in fully and properly loving my wife like that in the past - but I do realise what's expected and my own shortcomings in that.
