Are you financially faithful? New report reveals almost half of US couples have committed 'financial infidelity' — here's how to avoid a ‘profound loss’ by investing in your relationship

A new report from financial services company Bread Financial found that 45% of all coupled respondents have hid purchases from their partners. This proportion is even greater for Gen Z couples, with 53% admitting to financial infidelity.

Coambs adds that focusing on the acts of infidelity rather than what’s at the root of them can cost couples not just their financial security, but also their future.

Financial infidelity isn’t just about secret spending

Combs says everyone enters a relationship with implicit and explicit expectations around how they and their partner will manage finances — and financial infidelity is any breach of those expectations.

That can be spending more money shopping than you’ve mutually agreed to, buying a house without the other’s knowledge or secretly investing for retirement.

“The piece that makes it infidelity is not disclosing or talking about it and hiding it from your partner,” says Coambs.

Of the couples he works with, Coambs says 70% to 80% are dealing with financial infidelity, whether that’s why they came to him in the first place or it simply comes out in therapy.

It’s the same for Andrew Sofin, a psychotherapist specializing in couples and families in Montreal, Canada.

Sofin adds that most people think of sex when they hear the word infidelity, so in his practice, he’s found many are dealing with this issue without knowing what to call it.

The Bread Financial study indicates this can differ based on generation and gender. While 83% of boomers claim to have never hid a financial fact about themselves from their significant others, about 60% of Gen Z and millennials say they’ve withheld at least one piece of key personal financial information.

Gen Z is also almost twice as likely to have separate bank accounts compared to the boomer generation.

Men appear to be more prone to keeping money matters mysterious, with 3-in-10 concealing their credit card balance, compared to 19% of women. Over a quarter of men say they’ve hid their income, while only 15% of women say the same, and 21% of men aren’t confessing to their crypto, opposed to 7% of women.

With Sofin’s clients, the issue often shows up in relationships where there’s a power imbalance. People earning the lion’s share often feel the money is “their” money to spend how they see fit.

But whether they’re buying sports cars or lottery tickets, making those financial decisions without consulting their significant other widens that power gap.

“The person who’s not making the money feels totally dependent on the other person, and it has a major impact on their sense of self,” says Sofin.

Couples must get on the same page

What makes financial betrayals so painful is that money is not only a deeply emotional topic, it’s also tangible and crucial to our survival.

Another therapist once told Coambs about how her mother reacted when she found out her husband had gambled away their retirement fund: “She said, ‘I wish he would have cheated on me; that would have been easier to recover from.’”

“I wouldn’t take that statement literally,” says Coambs. “But … money holds representational value. It functionally means whether I have housing, whether I can access health care in the future, if I can buy food … And so when we get interrupted in that pathway, that's a profound loss.”

He also notes that financial infidelity looks different for everyone. In fact, we accept a certain amount of financial dishonesty in relationships. Surprise gifts for birthdays or anniversaries or splurging on a new love are common societal and cultural expectations.

However, Sofin counters that bringing home surprise flowers isn’t such a romantic gesture if you’re scrimping to pay your mortgage this month.
