It is said that men and women are equal, and I think spending money is equal. I think a girl can't just let boys spend money, because other people's money is earned by themselves, not by the strong wind or falling from the sky. I think a girl should be independent and can't rely on only one man, because he will leave you, but he won't use your own money. And a girl who is too dependent on others, I don't think anyone will like it.
I think when you are in love, especially at school, you should be clear about spending money. Because both of them are students, neither of them has any financial resources nor any income, of course, it is impossible for only one party to spend money. I think at this time, your boyfriend has no money, and it is ok for that girl to pay. I think both sides should understand each other and tolerate each other. Besides, girls look for boys to find a spiritual sustenance, not a material sustenance.
I think, between two people, about money, it is still necessary to make it clear. Of course, it doesn't mean we have to distinguish clearly. You can invite him to dinner today and invite him to dinner tomorrow, so as to pay him back.
