Why income? When two people are together, life costs money. Once they have no money, they are easy to quarrel. Everyone who has experienced it knows that. Secondly, after children come out, they still need education. He only has a junior high school education, and then the education of his children falls on you. If he has money, he can get a tutor, but he has no money, so you have to make money and educate, and then you feel bitter. This is my sister's practical experience, I hope I can help you.
