Entering the world of family life (marriage) does not mean we will enter the world of happiness, in their lives money is often an obstacle or a big problem in the harmony of their household. So in my opinion the main problem with finances is not a large income but not having an open attitude or not being honest about how much your husband's salary/income is. or one of the partners cannot change their mindset, life is always wasteful, etc. So what do you think? What is included in the red flag of household finances?
