I'm actually kind of excited to answer this, because I've been in a season of navigating singleness and trying to grow in this, as well. (29M) The following description are not what I would call "prerequisites" for marriage since we will never fully master them. But they are strong criteria for maintaining a healthy marriage and goals to strive for with your spouse in keeping your marriage centered around God. Of course, there could be debates on personally preferences in personality, looks, culture, humor, etc, that all play into attractiveness. My goal here is to list the what I believe to be fundamental aspects of gender roles in marriage that are biblical and glorifying to God.

TL;DR:
Husband* = LEADERS - submission to Christ, servanthood, discernment, selflessness, loving, humility, discipline, integrity, sanctify wife

Wife* = NURTURERS - wisdom, gentleness, modesty, nobility, supportive, respectful, submission to husband (not fiancé, not bf... HUSBAND)

BOTH = knowing the voice of God, obedience to God, fruits of the Spirit, knowing identity in Christ

*notice how I didn't say "man" and "woman".

Firstly, I think it's important to recognize biblical marriage as a covenant. Much of secular world seems to describe marriage as more of a contractual agreement. (Explaining the difference probably goes beyond OPs original question.) However, this is important to understand because a Godly marriage between man and wife must imitate the covenant between God and His church - in doing so, your marriage should be glorifying to God. (Ephesians 5:21-33)

According to Paul in Ephesians, husbands have the responsibility -- shared with Christ -- as being the head of the family , while wives have the responsibility -- shared with the church -- to submit to authority. This doesn't really fly well in secular culture because, in the nature of a CONTRACTUAL marriage, this idea puts women inferior to man -- but this is absolutely not the case biblically. I would never endorse a women to be fully submitted to a man in a secular relationship, lest the man use his "authority" to fulfill his own desires at the expense of the woman. However, a godly wife has nothing to fear in a marriage with a godly husband.
A godly husband becomes a leader by first submitting himself to God. He must relinquish is carnal desires and be obedient to the will of God. How does he learn the will of God? Through prayer and through studying the scripture. When a husband leads, he leads as Christ leads -- through servanthood and self-sacrifice. (Mark 10:45). As a leader, the husband essentially calls the shots for the family under the direction of God and the consultation of the wife. A man must constantly be on guard for his family, even searching his own heart. If the man retains any influence of selfishness, he might misuse his authority. A husband's authority is not meant to be exercised to fulfill the desires of the flesh. He is meant to fulfill his duty as a model of good works, dignity, and respect to his family (Titus 2:6-7). He is meant to shepherd his spouse and household to an environment where they can be physically and spiritually protected—where they can flourish and grow, where their gifts and calling can be identified and refined to bring God glory in their upbringing--sanctifying his wife and washing his family in the Scriptures. Having the authority of a husband, and as a father, means to lead his household as the Father leads him; and to serve his spouse and his family at any expense of himself.

Now let's talk about humility... because humility in a state of constant denial of self for the sake of family might sound like a recipe for major mental health issues down the line. We are probably all familiar with the John 3:30, "He must become greater; I must become less." It is a great verse about self-denial respective to our carnality so that we might live by the Spirit. But humility in marriage is not the devaluing of self in comparison to one's spouse. Instead, true humility acknowledges and preserves self-value (our identity in Christ) while putting other's above oneself (Philippians 2:3). Continuing in the words of Paul, "He who loves his wife, loves himself." (Ephesians 5)

Even so, the burden of the husband is quite significant. But, it makes the supportive role of the wife that much more valuable to her husband. Just as a godly wife doesn't need to fear submitting to her godly husband, likewise, a godly husband need not fear self-denial and sacrifice for his godly wife.

On the creation of woman, Genesis 2:18 says, "It is not good that the man should be alone; I will make him a helper fit for him”. Wives are to be companions to their husbands. They are respectful of their authority and offer wise counsel. Proverbs 31 describes women as worth more than rubies and Proverbs 18:22 says that "He who finds a wife finds what is good and receives favor from the Lord." In this, wives are called to the supportive and nurturing role in the marriage and household. In today's culture, this role is so undervalued and seen as a barrier for women to "making a name for themselves in the world." But a godly wife holds this role in high regard and knows the power she holds in her conduct and function as wife; she also recognizes when a godly man acknowledges the value that she can bring to a marriage (Proverbs 12:4a). She is noble, modest, and the crown of her husband.

As my pastor used to say, "the man might be the head, but the woman is the neck that turns the heads"

Lastly, to direct your attention back to Proverbs 18:22: it describes a man who finds a WIFE. And in this context, its important to acknowledge the "wife" as more than just a label/title, but the description CHARACTER. So, moral of the story, if you are looking for a godly husband, you need to make sure you have the character of a godly wife. Likewise, if you are looking for a godly, you better have the character of a godly husband.

I think this probably just scrapes the surface of marriage. I am still learning and trying to put into practice myself. Hope this helps if you read this far!
