My future parents-in-law are not very generous. I don't like them very much, because they are a little too stingy. They don't like me very much.

It is difficult to sort out the relationship between mother-in-law and daughter-in-law, not to mention that your in-laws don't like you very much. Maybe they care too much about money, so they cherish you. Maybe they should try to understand that it is more important to please filial piety, and maybe they will gradually accept you. If you don't handle it well, your husband will find it difficult to do it and may be suspicious of you. But in this matter, you and your husband did not handle it very well. He should speak for you properly, communicate with him and express your thoughts. After all, getting married is not easy. Don't make things worse.
