(Shutterstock) (Newser) – Infidelity isn't always the stuff of illicit affairs. A new survey shows that 31% of Americans who combine their finances with a spouse have lied about money to said spouse. "Financial infidelity may be the new normal," writes Jenna Goudreau at her Forbes blog. The most common misdeeds were hiding cash (58%), hiding minor purchases (54%), and hiding a bill (30%). But a decent number admitted to hiding major purchases (16%), keeping a secret bank account (15%), and lying about debt or earnings (11%). “Betrayal regarding money can be just as painful and damaging as other kinds of cheating," says a psychotherapist. It, too, can lead to "total loss of trust, feelings of betrayal and destruction of the relationship."
