Legal analysis: you don't need to return it together. The gambling debt of one spouse does not belong to the same debt of the husband and wife. China's laws clearly stipulate that gambling debts are illegal debts and are not protected by law. Therefore, if the lender knows that the money borrowed by the borrower is used for personal gambling, its creditor's rights are not protected by law. In other words, not only the spouse who has not borrowed money does not have to pay it back, but even the spouse who borrowed money for gambling has no legal obligation to pay it back, so the lender cannot sue the court to protect his creditor's rights.

Legal basis: People's Republic of China (PRC) Civil Procedure Law.
