If you think infidelity only occurs between the sheets, think again. It can also occur via secret purchases, hidden accounts, and slyly withdrawn savings. Experts call it “financial infidelity,” and it basically covers any monetary activity that partners hide from each other. Among couples who have combined finances, more than two in five people admit to hiding cash or bills or purchases, or outright lying about earnings and debt.

Whether you are dealing with a little white lie about a pair of shoes or a huge whopper like a hidden account in the Cayman Islands, you need to confront it head-on. First, have an honest conversation. It may be awkward but it’s gotta happen. Bring in a pro like a counselor or financial advisor if that helps. Then, set spending guidelines. Like, set the threshold for the purchases that require you to run it by your partner. And finally, take it seriously. 75 percent of people said financial infidelity impacted the relationship – leading to arguments, eroding trust, even sparking separation or divorce.
