Because a boy chased a beautiful girl for a long time, but he still didn't chase the girl in the end, which was something that made him very regretful and helpless.
So he thought of a way to make himself mentally self-consistent. Nowadays, girls are too material and love money too much. I really don’t want to get married.
is rationalized because I can't do it. It's like saying that the grapes are too sour when I can't eat grapes. In fact, it's because the fox is too thin, too small, not smart enough or lacks ability, and is found to comfort myself.
There are other examples in life. For example, if the college entrance examination fails, the student will shirke the reason to the teacher, saying that many questions have not been explained, or that the questions are set too biased, thus shirking their responsibilities.
I don’t like beautiful girls, but from a human perspective, no one in this world doesn’t like beautiful or handsome people, and no one doesn’t want to get married and have children. This is determined by everyone’s natural attributes.

Sour grape psychology exists in our lives, and the opposite of this is the chain of contempt, just like all kinds of relatives, friends, neighbors or others.
Because your life is better than others, you don’t post cars, houses or various delicacies in your circle of friends to show that you are superior to others.
Some people complain after seeing it, feeling that they live worse than others in all aspects, and thus feel inferior and cowardly.
Then some people develop a sour grape mind, like I don’t like such a big house, it’s too troublesome to clean it; now there is so congestion, I don’t like driving, etc.
From the perspective of objective and rationality, protecting one's own self-esteem and rationalizing one's own gap in this society is also a good way.
However, many people use rationalization to solve their incompetence in life. Although it is a mechanism to protect themselves, in the long run, it is a means of self-deception, which is not only deceiving others, but also deceiving themselves.
