What is the fastest moment to go broke in a relationship?

It's not encountering some earth-shattering betrayal.
It's when you suddenly tally up a "love economics" bill and hear the duet of heartbreak and wallet shattering.
That moment when the filter is instantly shattered by absurdity, it's truly deafening.
For example, during holidays, you grit your teeth and swipe your card to buy a luxury bag worth over ten thousand, only to get her shy smile in return.
She then gifts you something "thoughtful": a $30 plastic water cup with free shipping.
It's just "light on gifts, heavy on affection," emphasizing companionship.
The double standard and quick change of attitude would make a Sichuan opera master want to light a cigarette.
When it comes to buying a car, her first reaction is, "The car must be in my name for security."
You keep a cautious mind and tentatively ask if she can lend you a few thousand dollars for a quick turnaround.
The girlfriend who was just arguing about shared assets a second ago immediately clutches her wallet tight.
Instantly giving you a vivid lesson on scam prevention.
In the end, you still bought the car, but didn't add her name.
She comfortably sits in the passenger seat, enjoying the air conditioning, while delivering a blow to your ego:
"Look at you, old and ugly. Who else can tolerate you besides me? You should be grateful I didn't leave you."
At that moment, all I could think about was how the formaldehyde in this car was really pungent.
The so-called emotional PUA is essentially one side precisely harvesting your material wealth while mentally dragging you into the mud.
This is not love; it's precise targeted poverty alleviation combined with obedience testing.
