"considered just walking away" Well you can't do that. It is sinful for a Christian to end a marriage unless the woman is an unbeliever and leaves or if she commits adultery then you can divorce her keeping in mind that we commit adultery against God all the time but he doesn't divorce us as long as we repent.
Women are raised alongside men for 18+ years. There is according to society no such thing as gender roles. Women are totally destroyed by time they are of age. They are trained to be men, they are trained by every facet of life to be independent and if anything that men/husbands are dumb and stupid and should be mocked and have equal or in some cases less authority. At what point in all the worthless years spent in government indoctrination centres do women learn to be housewives, they used to have them but in most all cases they've removed such courses and options. Cooking and sewing and cleaning and baby-care and interior design is oppressive. Submitting and serving is gay, it's slavery, slay queen and strong independent woman who don't need no man are not memes they are the reality we live in. Likewise the reason Paul gives marriage advice is because clearly marriages weren't always what they should be even in his time. Submitting to your husband is not easy but does solve all issues assuming the husband is submitting to the Lord. Jesus is in the Father's hand, you're in Jesus' hand and your wife is in your hand.
You need to dig in and say "this is how things ought to be and I have the Bible to support me." Even an unbelieving woman overtime will submit to this yes I have seen it. Know this and make it clear: Everything is your fault. If your wife is disobedient it is your fault. And make sure she knows it is your fault. Anything wrong with your wife is your fault. If your dog bites someone I don't blame the dog I blame the owner. You took this dog in you raised it and you don't have a leash for it because he doesn't like leashes well now he has bitten me what do you expect. You're not a Calvinist are you? Therefore you believe every person can obtain salvation and by extension I would say everyone can be a great Christian and any two people on this planet can get married and make it work perfectly. It's not about finding the "right person" that's modern "dating" "relationship advice" nonsense. You purchase your wife just as Jesus purchases us at a cost. You should expect much work to do when you purchase your wife along with the rewards.
It's very frustrating that women don't submit. To get over this frustration first of all acknowledge we don't fully submit to God, your wife has been and continues to be brainwashed by a satanic society at every corner and also it is your fault if you haven't fixed her. Treat your wife as you want the Lord to treat you. I want the lord to be blunt and to chasten me. If you're in a relationship where "punishing your wife" is not even on the table then how can you say you're even married? If God can't punish me and if I get offended at the very idea then I have no relationship with him at all. And wives must submit to their husbands as unto the Lord in all things. But instead what we get are weak PUSSY (yes I said it) husbands who literally allow their wives to insult them in public constantly and indeed that's exactly what a wife will do when she has no authority over her, she'll bark like a dog all day and again: your fault. Does she belong to you or not?
With all these things, if you believe in Biblical marriage you need to be telling your wife that constantly. There is no "oh I hope it happens." This is about a devotion to God. If you have a poor marraige you're going to have to answer for it on judgement day, it would be better for you to push biblical marraige and for her to leave you than for you to live a non-biblical marraige. In either case you cannot leave, so make it clear what you want and don't give her attention otherwise, give her love as is commanded but if she is fully going to reject true marraige then basically give her the hint that it's either that or nothing more from you. In a two way relationship someone needs to have veto power. If both the wife and husband have equal authority then you're going to fight and eventually pretty much every time it'll break apart eventually. It's logical someone has top authority and the Bible says you have all the authority but also have commandments and duties to fulfil to your wife since you also belong to her. Explain to your wife why she has to submit, why she can't "jokingly" insult you why she should encourage you and that God created woman to be the helper to man. Women are not independent.
Submission is what every true christian husband complains about. And often women make it clear their issue is their husband isn't dominate to them though thanks to society are embarrassed to even consider it as that. There are some practical things you can do and things you can say, make sure you are always taking the lead and giving your wife love and for the love of the Lord husbands stop treating your wife as equal in marraige if you don't want that. Treat her almost like a child, she can't solve her issues, you have to do everything, you're taller than her for a reason: because you need to talk down to her as well as be the bigger man the better man and accept responsibility for all of her. I guarantee you can make your feminist wife wear a bonnet in public.
Make sure you are in submission to God first (or else how do you expect her to submit to you) and blameless and loving and not bitter to her. Jesus says you can't cancel the marraige which means he's going to fix it if you let him. Be very Christ-like around her, so important.
