What We Fight About When We Fight About Money
New research tackles the source of financial conflict and what we can do about it
3 min
When couples argue over money, the real source of the conflict usually isn’t on their bank statement.
Financial disagreements tend to be stand-ins for deeper issues in our relationships, researchers and couples counsellors said, since the way we use money is a reflection of our values, character and beliefs. Persistent fights over spending and saving often doom romantic partnerships: Even if you fix the money problem, the underlying issues remain.
To understand what the fights are really about, new research from social scientists at Carleton University in Ottawa began with a unique data set: more than 1,000 posts culled from a relationship forum on the social-media platform Reddit. Money was a major thread in the posts, which largely broke down into complaints about one-sided decision-making, uneven contributions, a lack of shared values and perceived unfairness or irresponsibility.
By analysing and categorising the candid messages, then interviewing hundreds of couples, the researchers said they have isolated some of the recurring patterns behind financial conflicts.
The research found that when partners disagree about mundane expenses, such as grocery bills and shop receipts, they tend to have better relationships. Fights about fair contributions to household finances and perceived financial irresponsibility are particularly detrimental, however.
While there is no cure-all to resolve the disputes, the antidote in many cases is to talk about money more, not less, said Johanna Peetz, a professor of psychology at Carleton who co-authored the study.
“You should discuss finances more in relationships, because then small things won’t escalate into bigger problems,” she said.
A partner might insist on taking a vacation the other can’t afford. Another married couple might want to separate their previously combined finances. Couples might also realize they no longer share values they originally brought to the relationship.
Recognise patterns
Differentiating between your own viewpoint on the money fight from that of your partner is no easy feat, said Thomas Faupl, a marriage and family psychotherapist in San Francisco. Where one person sees an easily solvable problem—overspending on groceries—the other might see an irrevocable rift in the relationship.
Faupl, who specialises in helping couples work through financial difficulties, said many partners succeed in finding common ground that can keep them connected amid heated discussions. Identifying recurring themes in the most frequent conflicts also helps.
“There is something very visceral about money, and for a lot of people, it has to do with security and power,” he said. “There’s permutations on the theme, and that could be around responsibility, it could be around control, it could be around power, it could be around fairness.”
Barbara Krenzer and John Stone first began their relationship more than three decades ago. Early on in their conversations, the Syracuse, N.Y.-based couple opened up about what they both felt to be most important in life: spending quality time with family and investing in lifelong memories.
“We didn’t buy into the big lifestyle,” Krenzer said. “Time is so important and we both valued that.”
For Krenzer and Stone, committing to that shared value meant making sacrifices. Krenzer, a physician, reduced her work hours while raising their three children. Stone trained as an attorney, but once Krenzer went back to full-time work, he looked for a job that let him spend the mornings with the children.
“Compromise: That’s a word they don’t say enough with marriage,” Krenzer said. “You have to get beyond the love and say, ‘Do I want to compromise for them and find that middle ground?’”
Money talks
Talking about numbers behind a behaviour can help bring a couple out of a fight and back to earth, Faupl said. One partner might rue the other’s tightfistedness, but a discussion of the numbers reveals the supposed tightwad is diligently saving money for the couple’s shared future.
“I get under the hood with people so we can get black-and-white numbers on the table,” he said. “Are these conversations accurate, or are they somehow emotionally based?”
Couples might follow tenets of good financial management and build wealth together, but conflict is bound to arise if one partner feels the other isn’t honouring that shared commitment, Faupl said.
“If your partner helps with your savings goals, then that feels instrumental to your own goals, and that is a powerful drive for feeling close to the partner and valuing that relationship,” he said.
A sense of mission
When it comes to sticking out the hard times, “sharing values is important, even more so than sharing personality traits,” Peetz said. In her own research, Peetz found that romantic partners who disagreed about shared values could one day split up as a result.
“That is the crux of the conflict often: They each have a different definition,” she said of themes such as fairness and responsibility.
And sometimes, it is worth it to really dig into the potentially difficult conversations around big money decisions. When things are working well, coming together to achieve these common goals—such as saving for your own retirement or preparing for your children’s financial future—will create intimacy, not money strife.
“That is a powerful drive for feeling close to the partner and valuing that relationship,” she said.

Elon Musk is exploring a potential merger between Tesla and SpaceX, a deal that could reshape the future of AI, robotics, autonomous vehicles and space technology. With a combined valuation potentially reaching $3.5 trillion, the move could bring Musk’s vision of an interconnected technology ecosystem closer to reality, although a deal remains uncertain.

Elon Musk has engineered ties between Tesla TSLA 3.41%increase; up pointing triangle and SpaceX SPCX 7.79%increase; up pointing triangle that are hard to break, and now he wants to fuse them together permanently.
Musk has run both Tesla and SpaceX concurrently over the past two decades, using a schedule that dictated which days he spent focused on each business.
The companies have often shared resources and personnel, signaling their close ties. Last year, SpaceX looked into creating a spacesuit for Tesla’s humanoid robot Optimus, a person familiar with the matter said. Tesla last week showed off its new Roadster, a vehicle featuring SpaceX rocket thrusters that it hopes to soon bring to market.
And in recent months, Musk has repositioned both companies by expanding beyond their core operations toward a shared mission centered on artificial intelligence.
The world’s richest man on Tuesday signaled his interest in tying up SpaceX and Tesla, marking what would be the biggest corporate merger of all time. Because he serves as chief executive of SpaceX and Tesla, Musk said committees of independent directors at both companies are evaluating a possible deal, adding that a transaction might not come to fruition.
The committees will likely evaluate, with lawyers and bankers, how each company would fare in a potential deal and how a deal might best be structured. They then present their conclusions to their respective boards, who typically vote on whether to proceed.
“It’s an odd Kabuki dance where two groups of people are talking and I can’t be in the conversation,” Musk told SpaceX investors on Tuesday in response to an analyst’s question about a potential deal.
For Musk, the merger supports his vision of a world full of autonomous cars, humanoid robots and weekly rocket launches, as well as the data centers and satellites required to keep the whole thing running.
Some investors and analysts said they expect a transaction would be structured as an all-stock deal, with SpaceX potentially paying a modest premium for Tesla shares.
SpaceX, which has a market value of about $2 trillion, said it is seeing sharp growth in revenue across its businesses, which include operating data centers, launching rockets and operating satellite networks such as the internet service Starlink. Tesla is valued at about $1.5 trillion and is expanding its operations beyond its automotive and energy business. Shares in both companies traded higher following the news Tuesday.
Musk’s substantial ownership stakes in both companies, along with voting control at SpaceX, has enabled him to set the deal in motion. Analysts and investors said the deal will probably face regulatory scrutiny internationally, though some see Musk’s close relationship with the Trump administration as an asset to getting approval.
Blurred lines
The companies haven’t said which directors are on the special committees evaluating a potential deal. Several SpaceX and Tesla board members have either personal or business ties to Musk. And like Musk, venture capitalist Ira Ehrenpreis sits on both boards.
In a filing this week, Tesla outlined millions of dollars in business agreements with SpaceX and its subsidiaries last year, including $143 million in car sales to SpaceX, $3.3 million in advertising that it bought on the social-media platform X and $430 million in revenue from the sale of Megapack batteries for SpaceX’s data centers.
The companies also split the cost of resources including the use of Musk’s SpaceX jet and the bill for his personal security, which he runs through a private company.
Employees at both companies routinely move between companies to work on special projects, and some executives have dual roles, including Charles Kuehmann, vice president of materials engineering at both SpaceX and Tesla, and Ashok Elluswamy, the vice president of AI software at Tesla who runs a joint venture with SpaceX called Digital Optimus.
Over the years, Musk has launched new startups within his empire, including brain-implant company Neuralink, underground-tunnel developer the Boring Company and xAI, the AI startup that merged with SpaceX in February.
It is that AI business that Musk thinks can serve a market worth tens of trillions of dollars, justifying the need for a merger.
The business case goes like this: Tesla is developing robotaxis and robots, which it calls “physical AI.” SpaceX is working on the back end of physical AI: the data-center capacity and internet connection required for those robotaxis and robots to operate continuously.
“I don’t see what the value of Tesla is if it’s not merged with SpaceX,” said investment adviser Ross Gerber, a former Tesla bull turned critic invested in both companies. “If they don’t merge, the brains of everything that runs Tesla is owned by another company.”
On top of it all, both companies face constraints on the supply chains they need to make this world a reality, particularly when it comes to chips. To address this, Musk earlier this year announced a joint venture between Tesla, SpaceX and Intel to design and manufacture chips in Texas. “The most epic chip-building exercise by far,” he has said.
Musk at the wheel
For Musk, a merger would also solve two problems: demands on his attention and his lack of control at Tesla.
Tesla for years was Musk’s only public company, a status that came with greater scrutiny. There, Musk reports to a public board, as well as individual investors who make up around 30% of Tesla’s voting power, according to FactSet.
The question of Musk’s attention became a particular focus for investors and the board in recent years after he acquired Twitter in 2022 and launched xAI in 2023, and again in 2025 as he spent time in Washington, D.C., running the Department of Government Efficiency in the early months of President Trump’s second term.
As Tesla’s car business suffered in 2025, Musk threatened to take his AI ambitions outside the company if he wasn’t granted 25% voting control. Last November, Tesla shareholders approved a new pay package for Musk, which created a path for him to vastly expand his stake.
As of Sept. 30, Musk owned a roughly 20% stake in Tesla, according to the company’s proxy filing.
The SpaceX IPO gave Musk a different path. When SpaceX went public in June, the deal’s structure enabled him to have more than 80% voting power at the company—so much that he can’t be fired and decisions can’t be made without his support.
If SpaceX acquires Tesla, he will likely stay in control.
