I hate my husband's brother.

Anyone who meets such a person will collapse. I suggest your husband talk to his brother. You are married. I don't know if your husband's brother is married. This is very wrong. Maybe he is used to being poor, stingy, petty and thick-skinned, but he has this habit and can't let you accept it. It's hard to say that your husband has lost face. You can give him a hard look or persuade him gently in the future. If he still doesn't repent at all, then his brothers will settle accounts and have less communication.
