Are you financially faithful? It might sound like a half-witted joke, but financial fidelity is real. So real, in fact, that it's one of the biggest issues tearing apart marriages and families. Some financial fibs might be considered 'little white lies,' while others are outright cheating. Either way, the discovery that you or your partner have been unfaithful with your combined hard earned cash will likely lead to an argument. It's common knowledge that money is the number one issue that couples argue about and therefore shouldn't come as much surprise that money is also the number one issue that couples lie about, not to mention the biggest issue leading to divorce. Different surveys over time have come up with similar results: about one-third of couples -- whether married, engaged, or living together -- have kept cash secrets from each other.

Here's what the most common financial fibs are about: 

• Gifts and Discretionary Spending 
• Credit card debt 
• Loans to Family and Friends 
• Hidden Savings 
• Failed Investments 
• Food and Drink 
• Earnings 
• Retirement Accounts
