I had a problem with my girlfriend and just sent me a text message saying; Let's calm down. what's the meaning

It means that your girlfriend suddenly feels tired and wants her to think calmly. Contradictions have become the fuse, making my girlfriend very tired and want to have a rest. At the same time, it also shows that she is looking forward to you, but the outbreak of contradictions makes her temporarily don't know how to face you and accept you now. She needs time to think. At the same time, you should think about whether you can accept, tolerate, respect and understand each other. This is the key to whether two people can live together. Ask your heart. I hope you can be good! Get to know her better.
