How to persuade my husband not to share a car with my brother?

In fact, the key is how you want to raise this car. What you think is very reasonable. Did you tell your husband?

I suggest that you don't talk to him about "persuading them not to buy a car", just saying that someone can buy it together, but if "my brother can't pay the loan for special reasons (such as unemployment, children's schooling, and parents' pension)", "can we afford to keep a car? How to divide this fee? " "Since my brother also loans, whose car is that? "

If he can find a reasonable solution for you, you can only admit it.

Your problem now is actually "the economic conditions at home are not so good, but my husband just likes cars and wants to buy them like a child" and "it is very troublesome to mix with my brother-in-law economically".

The first question was not considered because of lack of funds. But now that the two older children are together, there may be any disputes between them. This is what you're worried about. However, the problem of "husband has no concept of family, and everything must be mixed with relatives" cannot be solved in a day or two. It is likely that your husband will have to wait a long time for disputes and contradictions to realize this. Otherwise, you can tell him frankly, he will only dislike you and think of you.
