How far can AA couples go?

In real life, the husband and wife aa system is that the individual dominates the individual's salary, and the husband and wife have no basic trust.

One of my very good friends, at the latest to cry to me about the money her husband earned, she can't see a penny, her husband earns relatively more than her, because there is a child in the family, the child's expenses, or what is missing at home, her husband will buy it, or say well, you buy it, then I will transfer the money to you, he just says that he wants to buy a dress, or wants her husband to send a gift or something, her husband will say, Don't you also have a salary? Buy it with your own money! For a long time, his husband's family side of the matter, he basically no longer asked, the mother's side of the share of money, to his own parents to spend ah basically solve their own, and what they need to buy, solve it by themselves. Because she earns not less herself, so she can still accept it!

Some time ago, my friend ah, his mother found out that it is breast cancer, found it earlier, on the hospitalization, radiation therapy, chemotherapy, basically the condition has been stabilized. He took leave to take care of it, because he took leave plus the cost of medical treatment, and the money in his hand was nervous at once, although her mother took the big head, but she also spent a lot of money here, plus the leave of absence These months the salary has not been opened much In the hand, it is a little nervous! Her husband began to take 10,000 yuan, and basically did not pay for it later. The two began to have a conflict, she said that she did not see a penny of his husband, her husband said that I spent all the money at home, you see the children and household expenses are I am spending. I don't have much left! My friend cried several times and said oh, I want to divorce him and live like this, it's so boring, it's pity for our children! Tell me that I can only soothe her, auntie's body is recovering, should bear with it! Back to your two mouths to communicate well! In fact, in this case of the two of them, I don't know how to persuade them.

As the saying goes, husbands and wives sing along, husband and wife are in the same heart, if this kind of couple can't do it, how far can their AA marriage go?
