Not getting married or being childless?

 　　I'm 23 years old this year and have had three boyfriends. The first one was in my first year of high school, but I broke up with him after about a month because I felt he wasn't mature enough. The next two were after I turned 20, and they started discussing marriage and children with me after less than two months. I admit that I broke up with them because I'm afraid of marriage and don't want children.

　　Growing up, I've never been well-regarded by my parents, whether in studies or life. They've almost never felt that I brought them joy; it seems like my arrival in this world was a cruel punishment for them. Therefore, I've never thought about having my own children in the future because, based on my personal experience, I lack the confidence to be a good parent, not to have too many expectations of my children, and to be able to selflessly dedicate myself to them. In this regard, I don't care what others say; after all, life is your own, and only you know whether you're happy or not.

　　Ironically, at this point, my parents are telling me to find a partner, get married, and have children as soon as possible. They have clearly experienced all the unpleasantness of raising children and regretted bringing me into their lives, yet they want me to experience the same unhappiness they went through. Why? Is it because of love? Is the responsibility of procreation really that important? In parents' hearts, their daughter's happiness is less important than the opinions of their extended family. For example: "Why isn't your daughter/son dating yet? Why isn't she married? Is there something wrong with her? Does she have some serious illness?" Sometimes, they are more afraid of others' judgment than of their children's true feelings.

　　Ultimately, humans are still animals. People without much education don't think about the meaning behind our actions. They can hardly accept being different from others; they don't even understand why they're doing what they're doing.

　　Isn't this a failure of social development?
