If the other person's parents are rich, and your boyfriend earns just so much, so be it. Don't get married just because you think the other person has "good family conditions". Because his parents are his parents, which has nothing to do with you. You can't expect his parents to subsidize you all day while you are married. In addition, in the case of shortage of manpower and financial support from parents, you may get involved in your life.
If the other person's family conditions are average, but your boyfriend is good at making money, then I suggest you investigate the feelings and behaviors of the other parents. Some families, parents, especially mothers, have poor family conditions, but boys are very motivated and admire their sons, thinking that which girl marries her son is simply a blessing in the last life.
If his parents don't have a good relationship, then the mother will mostly pin her feelings on her son, and subconsciously feel that her daughter-in-law is here to rob her son. Therefore, if your boyfriend is good at making money, but his family conditions are average, you should visit his parents.
After some ups and downs in life, I feel that people are the most important. For example, people with money at home are relocated households. If a person or family member has bad habits, makes friends carelessly, likes gambling, etc. It may be gone in a few years. Many social idlers are staring at these nouveau riche who are "unworthy of virtue".
A person's moral character depends not on what he says, but on what he does. You can adopt some specific small things, "being more critical and seeing the big with the small". From the clothes, you can see his taste; A few trips to the mall will help to understand his living environment. From the details of life, we can see whether he is atmospheric; From his daily social interaction, we can see his communicative ability; From the depth of the chat, we can understand the breadth of his thinking.
In fact, the troubles caused by family factors are all details, such as consumption concepts, views on the status of men and women, health habits and so on. If you all meet these aspects, the difference in family conditions should not be particularly great. If your boyfriend doesn't pretend to be himself.
