The process of how discord accumulates between a man and a woman after marriage

‌Fundamentally, a man gives his all to someone who believes in him.
Similar to how he received comfort and strength from his mother (parents) during his childhood and growth, once married, if his spouse or family encourages him when he is struggling, he gains the momentum to push forward once more.
However, while this might not be noticeable in the early stages of marriage, as they have children and have to manage work, family, and extended family, men often find themselves in situations where they are stretched too thin. Especially in fulfilling the role of the breadwinner through employment or running a private business, if things do not go well and they go through a difficult process, there comes a time when they want to give up everything.
On the other hand, from a woman's perspective, she wants him to earn well on his own, wants him to be good to her own parents, and wants him to take care of her on birthdays, anniversaries, and so on. If he fails to do these things, there are cases where she might say, "Why don't you know these things? Shouldn't you just know what to do?"
Then, the man loses his strength. He thinks, "I have been running myself to death for the sake of the family, so instead of giving me just one word of comfort that I need, why are you only talking about your own position?" He begins to doubt, "Is this not a marriage based on love, but a life like a shackle where I can only be recognized if I meet certain conditions??"
He feels a sense of skepticism, thinking, "This woman didn't marry me because she loves me, but she is only demanding that I change this and that to fit the mold she has created." From that point on, the man and the woman begin to look in completely different directions.
And even if he endures and moves past it, if such discord accumulates, he may eventually end up as a "discarded male" who is ignored (cast out) from the family structure.
I leave it to each of you to think about what kind of mindset a man and a woman should have when getting married so that they can live happily for a long time.
