Start by supporting your partner, then financially adopt them.
That’s exactly what a 25-year-old woman found herself doing when her 27-year-old boyfriend asked her to co-sign a car loan. He said he needed a work car. What he didn’t immediately mention was that he had already saved for a down payment until he spent the money on a PlayStation 5, designer sneakers and weekend trips with friends.
In a post on Reddit, she explained her rejection. “I told him no, I wasn’t going to risk my credit when he had just proven that he couldn’t manage his credit,” she wrote. His reaction? “He said I didn’t support him and didn’t believe in his potential,” she said. Then comes the even better thing: “Now his mom is even texting me saying I should help him because that’s what partners do.”
Don’t miss:
The poster admitted that guilt began to creep in. “I started to feel guilty,” she wrote, “but I’m not a bank either.” Still, she questioned whether her refusal was a mistake.
There are answers on Reddit, but none involve her signature.
“His ‘potential’ means nothing if he chooses a PS5 and sneakers over reliable transportation,” one commenter wrote. “He’s not a partner; he’s a financial burden. The fact that his mom is texting you to pressure you is a huge red flag.”
Another added, “If his own mom won’t sign it for him, why would you? Don’t do it, girl!”
The user was not only concerned about her credit, but also expressed dissatisfaction with the relationship itself. “She needs to end this relationship now! He and his mother have given her every reason to believe this is a very unhealthy relationship,” one commenter wrote. “If she stays, she’s going to pay the price.”
Others point out the absurdity of emotional manipulation. “Believing in his potential doesn’t mean signing legal documents for a guy who just spent his savings on luxuries. He doesn’t need a co-signer. He needs accountability.”

From a financial perspective, co-signing is more than just a gesture of support. This is a legal contract that makes both parties equally responsible for repayment. If he stops making payments—or never starts making payments—the lender goes after the co-signer. Late payments affect both credit scores. The collection struck two names at the same time. Even if you break up, the debt won’t disappear just because the relationship is gone.
This is exactly the nightmare many commenters warned about.
“Imagine this: a few months later he spends the money on more crap and then says he can’t pay for the car,” one user wrote. “Your credit is on the line, so you have to pay him. He didn’t like the job and quit. Now you’re in trouble. He had a car accident and was completely broke – and you still have to pay. He gets in the car, breaks up with you, and leaves. You have to pay for his car.”
Some speculate that his mother knew the risks and was moving away from it. One netizen wrote: “Either her credit is crap too, or she knows he will default and doesn’t want it to be her problem too.”
Others offered blunt facts. “Sorry…at 27 he has no potential,” one user wrote. “That’s a boy. Run.”

It’s a fair reminder: Your credit report shouldn’t be shared with the person you share a bed with—especially if they’ve just proven they can’t manage a savings account without spending it on video games and sneakers.
According to TransUnion’s Credit Industry Insights Report, the auto loan delinquency rate increased slightly to 1.45% in the third quarter of 2025, up from 1.41% a year ago. With interest rates and vehicle costs remaining high, it’s not just bad luck that causes borrowers to default, but poor decisions.
When someone sees “potential” as a personality trait but is unable to prioritize basic bills over luxury spending, that’s not a risk for your loan. If your finances are in good shape, protecting your credit isn’t selfish, it’s smart. Consulting a financial advisor before associating yourself with anyone’s debt is a responsible move, especially when the stress is emotional and the consequences are legally binding.
When his mother tries to guilt you into solving the problem? That’s not a partnership. That’s a warning label.
