First, care too much. First of all, a lifestyle like AA will seem too concerned. Now that they are husband and wife, it shows that they have passed the test of money together and decided to accompany each other in their later lives. The pre-marital AA system is actually understandable, because no one wants to waste too much time and money on a stranger before the relationship is determined. However, after marriage, many couples adopt a salary-sharing lifestyle. Whether it is rent, water and electricity or car loan, mortgage is shared by both husband and wife, which reflects the value of marriage and is to face these problems together. AA system is too cumbersome, and it is not too expensive for family dinners, so AA is not needed.
Second, feelings will become alienated. There are many examples of marriage in reality that AA marriage will not last long. Because in a relationship, what we should care about is the mode of getting along with each other, and the emotional state is not how to share the expenses. If the husband and wife only pay more attention to how to distribute the expenses equally, some contradictions will gradually arise. After all, these expenses can't be divided equally in any case. Even people who have lived for a long time will have many contradictions, not to mention money. Therefore, if many consumption activities in life are carried out under the AA system, the relationship between husband and wife will gradually become alienated and indifferent.
Third, the AA system will make couples pay more attention to money. AA system will make couples pay more attention to money, who pays one month's rent more, who pays one month's mortgage less, and so on. These problems will gradually become potential contradictions between husband and wife and become the fuse of marriage failure. Because in their feelings, what they care about is no longer the emotional state, but how to use money on average. AA system can't solve property disputes, but it will cause emotional cracks. People who really live together and want to go on for a long time should not pay attention to these. We should face the difficulties in life together, encourage and protect each other, and don't be so clear about money.
Fourth, AA is unrealistic in marriage. In real life, especially in marriage, it is unrealistic to implement AA system. Many couples can't do all the expenses AA. The ideal way of property management is that the husband and wife jointly save a sum of money every month as the fund for investment and financial management, and the rest is at their own disposal.
