It isn't about women who aren't working it's complicated. If you don't have a partner who's sharing the same ideas you're going to get hurt. If one's saving & the other's spending it's going to end with breaking hearts. You've got to marry after you're sure you've got an understanding.
Generally, you have to prepare yourself before getting married. If you have any mistakes in yourself, you cannot blame those mistakes on your partner. Remember that your partner may not be an expert than you, so she needs to create an economic chart of how you will spend your income and how you will spend it in the family. If you make your wife financially competent and aware, then your family will definitely be happy and you will be financially secure. But if you yourself are not financially aware, you will never be able to achieve financial security just through your wife.
