Abdul, it means to stop dividing money as if roommates. You share the same household, so all money belongs to it. Therefore, you communicate openly about money coming in and when you or your wife wish to spend outside of the typical bills. You don't have a mine is mine and yours is yours mentality about money. Financial intimacy involves ultimate trust because regardless of who makes more or who manages the bills, all money goes into the same pot (bank account), nothing is hidden and everything is disclosed. Getting to this point really creates a partnership, quells deceitful behavior and arguments about money, which affects positively every other aspect of marriage. It truly comes down to an attitude adjustment and both spouses feeling supported. Pray that helps.
