My girlfriend spent a lot of money on me. I'm sorry. What should I say?

If your girlfriend says that she spent a lot of money on you, and you are sorry, then you don't have to spend it on him. You just need to give him some money on appropriate festivals, let him spend the cream himself, and tell him that the money is for your pocket money. You don't need to tell me how you handled it. Yes, that's good. When two people are together, they don't care so much about money Two people are together because they are happy, like each other and love each other. So it doesn't matter who spends more or less, but you must have a steelyard in your heart. Sometimes a girl doesn't care about spending more money on her boyfriend, but whether she knows how good he is to you, so you must be kind to her, maybe give him some surprises, maybe give him some comforting hugs on some fixed occasions, which can express your love for him.
