My girlfriend and I quarreled and wanted to send her a message, but I didn't know what to say.

Apologize is to get rid of responsibility, accuse me of being wrong, and promise to resolutely correct it. You can forgive me! But if it is the fault of the other party, then if you apologize again, she will do whatever she wants and indulge too much! The point is: the dance of love needs the tacit understanding of both sides to accompany each other. Even if you dance, she won't participate, which is equal to 0, duck egg love!
