Because things like home appliances usually cost thousands of dollars, they need to be purchased at one time. Maybe some couples with great financial pressure really need to use credit cards to solve the problem, but when they need to use credit cards for meals, sometimes they really need to think about it. Are such economic conditions still suitable for falling in love? And if you don't even eat half the price of a person, does it mean that you have to cut things in half when you eat, so you won't eat them in the future, and the other party thinks it's unfair?
So I think if it is a big expense, two people should share it, even after breaking up, they should share some pressure for each other. Otherwise, it's a bit like bullying each other, but if you have to draw a line with each other's eating, drinking and having fun, then in fact, this relationship has drawn a line before it begins. Not two close people, just two tenants who live together. You should count them one by one after separation.
In my opinion, the reason why couples can be called lovers sometimes includes the factor of being taken advantage of by each other. So after breaking up, some people will make a list and ask the other party to repay the expenses. This kind of behavior is very ridiculous to many people. It is no different from such behavior to swipe a credit card to solve daily expenses and pay them back together after breaking up. In my opinion, there shouldn't be such a fuss in intimate relationships.
