Some possibilities: Their flashy car may be on hire purchase and one week away from re-possession. Their "condo" could be rented and they have not paid the rent for last 3 months already. Their credit card bill not paid and credit card debt is up to $100,000. Their flashy name card "MD" title is fake. They have a terrible gambling habit and an alcohol addiction which they hide from the girl for the time being. They are prone to violent rages and wife beating after marriage.
