What should my wife do if she likes to find fault more and more?

First of all, my opinion is that I don't recommend living alone (the implication is that I don't approve of divorce), because you are not old now, and there is still a long way to go. There are many other big things and small feelings when a person takes care of the children. What do you do when you think your children are in trouble? Pat your ass and leave, just like now. Will you be separated from the children? You might say, no way, this is my own son. How can I kiss him like this? Then I ask you to think back to a few years ago. Do you love your wife less than your son now? And if you promised your wife, did you think you were lying to your wife? But in just a few years, your idea has become like this. You still have decades to live, and your son needs your care for at least ten years. If you think you can guarantee it, it won't stand the test of trivial things. So don't just make a decision on a whim, but fully consider the whole journey of life. So it is not recommended to break up because of these things.

Of course, since we don't break up, we have to find ways to improve the relationship between husband and wife. This is called management. Marriage also needs to be managed, so we should learn and explore ways to manage marriage.

My idea is to start with myself first. Are you sure you can't find anything wrong when you do things? Have you noticed any change in yourself? If you can't find it, you can talk to your wife about the changes since you got married so long, and talk about her vision and planning for the future of your family. You don't need to work together, and you can always find a preservative for marriage (a method suitable for your marriage relationship).
