To tell the truth, as an adult, when you buy a house for your brother without telling your wife, you should think of what your wife would do if she knew about it. Now that your wife knows, isn't it a little late to find out that your wife is separating or divorcing you? Everything in this world is sold except regret medicine. Now that the wife has made a decision, it depends on how she views marriage and buys a house for her brother.
If your brother is disabled or can't take care of himself, as a brother, he has the ability to buy a house for his brother. It is wrong to buy a house for my brother who can't take care of himself without telling his wife, but it is understandable. If his wife does not forgive his wife and insists on separation or divorce, it is his fault. After all, his brother can't take care of himself, so it's no problem to help him. So, if that's the case, after all, you have a pre-announced agreement to talk to your wife once and bow your heads and admit your mistakes. My wife is probably not a rude person and will forgive you.
But I'm afraid your brother is a man with sound hands and feet, and even has the problem of eating old people. He couldn't afford to buy a house all day, and finally for some unspeakable reasons, you bought a house for your brother without telling your wife. If so, it's not too much to divorce on the spot, besides, your wife has packed her luggage. If you use the money saved by you and your wife to buy a house for your brother, then you have gone too far. Although you and your brother are related and blood is thicker than water, you and your wife have a good relationship. Doing such a thing without telling your wife is no longer a matter of money, but that you don't treat your wife as one of your own.
So, if you still think there is nothing wrong with what you did, don't blame your wife for her extreme behavior. If you think you made a mistake in buying a house for your brother, set an example. My brother can't take care of himself. You can buy him a house. This makes sense. But if your brother is a healthy person, why not make money to buy a house by himself? With the money saved by the husband and wife, you buy a house for your brother. You don't take your wife's efforts seriously. If you think your wife is a qualified wife, if you still want to keep this marriage, talk to your brother once. Getting your money back is an explanation for your wife. If you don't want it back, I hope you can respect your wife's choice. After a piece of paper is wrinkled, no matter how it is smoothed, the wrinkles still exist, as do the emotional cracks between husband and wife. Since you have done such a thing, don't blame others for being heartless.
What is husband and wife? Husband and wife are two people who want a better life. I don't agree with you. It's generous of you to settle accounts with your brother.
