Of course, each person has their own life, and there is no right or wrong with that life. Compared to others, this life is good, and I'm just suffering because I don't like this kind of life without permission.
Certainly, people who want children, and who have children suffer from each other by putting their values, such as wanting boys, wanting girls, and not having children, as if they were true.
Since ancient times, Japanese people feel pressured by those around them when they get married, and I think it's a bad habit to be a child. They are bad because they are imposing their own wrong values and the wrong values of the world. Please be aware that even if many people say yes, there are things that are out of touch with the truth.
Children are not something you have to give birth to, and you should be able to live a satisfying life even if you don't have children.
If you really want children, you can adopt them, so why don't you live a way of life without being swayed by the wrong values around you?
Also, I want you to be aware that you are creating your own suffering. As for your cousin, your cousin isn't hurting you; your cousin just comes to your parents' house. You are creating jealousy and suffering by watching it. Comparing people without children causes suffering. You have your own life, so please live your own life and practice instead of interfering with other people's lives.
