Tell me why my dad thinks he must get married.

It can be seen from your description that your father may think that marriage is the only way of life and a traditional family value. In China culture, getting married and having children is regarded as an important part of family responsibility and inheritance, and many people think that marriage is one of the signs of a person's growth. In addition, some parents may think that marriage can also bring stability and happiness to the family, and at the same time, it can also add offspring to the family and continue the family bloodline.

In addition, you mentioned that your father once asked you to give up your studies, probably because he had different expectations and plans for your future. In some cultural backgrounds, parents may think that their children's future should be controlled by them, or they may think that their children do not have enough judgment and ability to make correct decisions. Therefore, when you choose not to get married, it may be seen as a violation of their expectations and plans, leading to a fierce quarrel.

Whatever the reason, it is important for you to communicate frankly with your father and express your thoughts and feelings. You can try to explain why you don't want to get married, your plans and pursuits for the future. At the same time, you can also try to understand your father's thoughts and opinions and keep an open and understanding mind. Through mutual understanding and communication, better communication and relationships can be established.
