My girlfriend got angry and said she wouldn't contact for a week. Let's calm down. In the meantime, I sent her a message, and she rarely responded coldly. She joked with her and told me to be serious.

That was her angry words. If you don't let contact, you really have to contact. If texting is not good, you'd better call and say it beautifully. No matter what she says about you, you should be a ninja. Some girls had better not play jokes on her when they are angry. Sometimes she takes it seriously, but usually there are only three things. Girls are just that kind of temporary anger, just want you to care more about her.
