"It was arranged quickly for my mom's 60th birthday"... Boyfriend drains couple account to send his parents on a trip [What do you think?]

[Financial News] A boyfriend who is dating his partner with marriage in mind has sparked controversy after spending money from their jointly funded "couple account" on a trip for his parents without consulting her.
The story came to light through a post uploaded to social media on the 28th. The author asked what people thought of a boyfriend who sent his future in-laws on a trip using a "dating account" they had funded with marriage in mind.
According to the post, A had been depositing 500,000 won a month into a dating account with her boyfriend for the past year. After saving nearly 4 million won for an overseas trip marking their third anniversary, A logged into the app to book plane tickets and discovered that only 130,000 won remained in the account.
A hurriedly checked the withdrawal history and was horrified. She found that more than 3 million won had been charged the previous month for a five-star hotel on Jeju Island, a rental car and four plane tickets.
When A immediately called her boyfriend and demanded an explanation, he admitted that he had paid for a family trip he took with his parents the previous week using the card linked to their dating account.
A strongly protested, saying, "How could you spend all our travel money without even saying a word to me?" But her boyfriend responded indignantly instead.
The boyfriend raised his voice, saying, "A trip was arranged at short notice for my mom's 60th birthday, but I didn't have a lump sum readily available," and, "We're getting married next year anyway. As your future mother-in-law, can't you contribute even that much toward your future mother-in-law's 60th birthday trip?"
He added, "I'm sorry I spent it without telling you, but honestly, I'm turned off that you treat me like a thief over money I spent on my family."
When A demanded, "When did I ever say I would pay for your mother's 60th birthday trip? Restore the 3 million won immediately," her boyfriend instead expressed his disappointment, saying, "It's frightening how calculating you are about separating your money from mine when we're about to become family," and, "You could just pay it back gradually after we get married, but you're being so petty."
Netizens who saw the post were outraged. Most strongly criticized the boyfriend, commenting, "Get your money back and break up with him no matter what," and, "This is what people mean when they say your ancestors were looking out for you."
Some netizens pointed out, "Whether it's a dating account or a group account, using money jointly saved for a specific purpose without permission is clearly embezzlement." They advised the couple to leave clear evidence that they had both contributed a set amount and had agreed to use the money only for mutually agreed purposes.
