you justifying the action is part of the problem. Your brother is a spineless cuck who would rather rob his own family than confront his wife about her spending
He does confront her, sounds like they fight constantly over lots of different things. He just doesn't know how to make her cooperate. She simply won't. She either does things her way or makes his life even more miserable.
Work in progress, please be patient.
