From an economic point of view: how much can he spend for you when you go to college for four years? You should know that your nature is surrogacy, and you should know that it is illegal. Even so, it costs 500,000 to 600,000 to have a child by surrogacy, so it is not economical.

Ethically speaking: since he wants a son, can you guarantee that you will have a son? What if he doesn't want a daughter? Did you bring it yourself? Not only that, you went to college before you got married, so you gave him a child. What do your relatives and friends think of you? This will devalue your value. Although you won't feel anything in college for a few years, you will find that your life will be bleak when you enter the society, because you are not responsible for yourself, and there will be great problems in getting married for the rest of your life. Because it's mixed up, you have to pay it back sooner or later!
