My boyfriend said more than once or twice that he didn't bring a meal card, so I gave it to him, but all the things he bought were things he didn't usually see.

You mean boyfriend friendship is stealing from you? Is to see things that you usually like but are reluctant to buy, deliberately say that you don't have a meal card, and then take your meal card to brush money. He can't bear to buy it himself or brush the money himself. Indeed, if so, then he is really stingy. When two people are together, even if you and I don't care, that boyfriend can't deliberately put on your oil like this. Why are you sneaking around like this? Is her family condition much worse than yours? So she always wants to scrimp and save to see if you eat well, but she can't bear to eat because she can't afford it and is afraid that you will look down on him. Do you feel inferior? So what caused her to become like this?
