Infidelity with another person isn’t the only kind of cheating that takes place in relationships. Sometimes betrayal isn’t romantic at all.

Imagine your fiancé, despite a more-than-comfortable income of $112,000, has been quietly carrying $35,000 in credit card debt — debt you knew nothing about while planning a wedding, planning to buy your first home, and mapping out a shared future. When the truth finally comes out, the shock isn’t just about the number. It’s about keeping money secrets — aka, financial infidelity.

Turning 50 with $0 saved for retirement? Most people don’t realize they’re actually just entering their prime earning decade. Here are 6 ways to catch up fast

Cheating breaks a promise, and so does hidden debt. And on top of breaking your heart, it can also break financial security and rewrite years of joint decisions made under false assumptions. And as uncomfortable as it is to admit, financial dishonesty isn’t rare. It’s a continued concern at a time when credit-card debt is surging and the cost of everyday life is stretching even high earners to their limits.

It’s easy to imagine that the people most likely to hide debt are those barely scraping by: a recent graduate who misused credit cards, or a parent quietly using credit to keep food on the table. But the data tell a different story.

A recent survey from LendingTree found that higher-income Americans are more likely to lie about credit card debt than lower earners. Among people making six figures who carry credit card balances, about 50% admit to lying about that debt. By comparison, just 39% of people earning under $30,000 said the same (1).

In other words, the person hiding debt isn’t always struggling to survive. Often, it’s someone who looks financially successful on paper — steady income, decent lifestyle, maybe even savings — but is quietly carrying high-interest balances.

Shame plays a major role. High earners may feel they should know better, or worry that admitting debt will puncture the image they’ve built with a partner. Instead of facing the discomfort, some choose secrecy.

That secrecy is becoming more dangerous as credit card debt balloons nationwide.

According to the latest household debt data from the Federal Reserve Bank of New York, Americans now carry $1.23 trillion in credit card debt, a record high. That figure is up nearly 6% from a year earlier. This suggests the cost of living isn’t just hitting people at the margins; it’s creeping into middle- and upper-income households that once felt insulated.

Many partners discover secret debt the hard way: when applying for a mortgage together, when a loan is denied, or when a bank flags an overdrawn joint account. By then, the financial damage is often compounded by emotional fallout.

About 40% of Americans admit to some form of financial infidelity, or keeping money secrets from a live-in romantic partner, according to a 2025 survey from Bankrate. It’s defined broadly and can include hidden credit cards or bank accounts, undisclosed spending, or undisclosed debt.

The emotional impact can rival that of cheating. Money symbolizes security, trust, and shared goals. When one partner hides debt, the other is unknowingly making life decisions based on false information.

If credit card debt has become overwhelming, secrecy is not likely to help. Shame keeps people stuck. Transparency creates options.

"Money secrets can undermine a relationship,” said Bankrate senior industry analyst Ted Rossman. “It's hard enough to meet your financial goals when you're pulling in the same direction, but it's almost impossible if you're pulling in opposite directions” (3).

The first step is brutally simple: come clean. That conversation will be uncomfortable, but it’s far less damaging than letting a partner discover the truth on their own.

Next comes action. If high-interest balances are spiraling, debt consolidation may help. Rolling multiple cards into a lower-interest personal loan can reduce monthly payments and create a clear payoff timeline, as long as new balances don’t creep back in.

Another option is working with a nonprofit credit counseling service. These organizations can help negotiate payment plans with creditors and reduce interest rates without the severe consequences of bankruptcy.

Bankruptcy itself may be an option in extreme cases, but it’s not a reset button. It can devastate a credit score and make future borrowing far more difficult for years. It should be viewed as a last resort, not an escape hatch.
