My girlfriend asked me not to send her messages. What does that mean?

If your girlfriend asks you not to send her a message, it means that she is already disgusted with you, or that your contradiction has reached an extreme during this time, and both sides need to calm down at this time.

You can wait for a while, don't send a message to contact him for the time being, and let both sides calm down. If it is your own fault, then take the initiative to contact her to apologize after this period of time. If it's the other person's fault, then you should take the initiative. A man should be broad-minded and try to learn to tolerate others, especially his girlfriend.
