Asking someone to hold your money is a sign if you're have a bad money management and they should teach you instead of agree to hold your money.
I think there's nothing wrong with entrusting someone or one of our families, be it our wife or mother, to manage finances so that they don't run out easily because of gambling or waste in financial management. I admit honestly that indeed I have bad financial management
Man, I'll tell you, entrusting your money with your wife is not wrong and never was. What's wrong is, when you're not sharing your money with your wife. I mean you two have conjugal property, what you earned is also her property. Women who don't have day jobs and a full time mom usually has a very good financial management. So these wives are most probably going to help you control your unwanted spendings in gambling. Therefore, there is absolutely nothing wrong with it. Also, if you're married I don't think entrusting your money to your parents is necessary. Not sure about your culture, but in my country that's definitely a big insult to your wife, except for a wife who has bad financial management, usually these are the kind of wives who would also like to gamble.
