10 signs your spouse is secretly spending money

Maybe you've noticed a mysterious lipstick print on his collar. Or perhaps she's suddenly working late and on weekends, without any apparent promotion or change in job duties. The signs that your spouse is seeing someone else may not always be easy to spot, but there are a few key signs.

But what if your significant other is sneaking around, not with someone else, but your bank account?

We asked several financial and relationship experts what some of the telltale signs are of a money-cheating spouse. Some of these are obvious; others, not so much. If you're concerned at all that your significant other may be secretly spending, check out the list below. Just remember that while one red flag isn't likely cause for alarm, positive answers to two or three of these signs could mean you have a spouse who's a secret spender.
