"The biggest business decision you'll ever make is picking your romantic partner." One of my wisest former editors told me this, and the advice has always stuck with me. I've shared it with my circle of friends, and it's become a sort of litmus test in our group.

Whenever we're considering a serious relationship with someone, we ask, "You love them, sure — but would you want them to be your business partner?" It's not always a dating dealbreaker , but it's a fair question to ask — especially if you're considering consolidating bank accounts. Merging money requires not only trust, but a ton of understanding and open communication. There are certainly benefits, but it's also easy for things to go awry.

In a recent survey of 1,659 people by the financial services company Bread Financial , 48 percent of coupled respondents who shared a bank account with their partner said they were surprised by what they found when they merged finances. When it comes to merging accounts, "surprises" aren't ideal, whether they involve a low credit score, debt, a Temu addiction , or tons of money tied up in "buy now, pay later" purchases . (Even a good surprise — like finding out your partner is secretly loaded, as in the case of George and Callie in "Grey's Anatomy" — may signal some subpar communication habits in your relationship.

) If everyone is honest and shares openly, though, it lessens the chance of major surprises popping up when you take the big step of merging accounts, says fina.
