Treat others in their own way. If she doesn't reply to your message, don't reply to her message either. Let her feel what you feel and she can better understand what you feel. Then the two of them have a good talk.
I think some things cannot be solved by just relying on communication and talking. Just like the situation between you and your girlfriend, she always doesn’t reply to your messages and you are very angry. I think you should have talked with her before. She has talked about this problem, maybe she explained and guaranteed it at the time, but nothing has changed since then. So, if communication doesn't work at the beginning, you need to repay the other person the same way he did, and let her feel it too. How it feels when others don't reply to her messages, so that she can experience what you feel, and it will be better if you talk about it together later.
I also hate sending messages to others, and they don’t reply, so generally when others send me messages, no matter who they are, I will reply, even if it is an emoticon, I think this is a matter of politeness. , Ignoring other people’s messages is very rude and hurtful. It’s not like you have to cling to someone, and you don’t have to go to someone when you have nothing to do. There must be a certain reason for asking you to send you messages. Since you often don’t Reply to me, then I don’t want to talk to you anymore. Who doesn’t have a little bit of arrogance?
So for you and your girlfriend, if she doesn’t reply to you, stop looking for her. You have done your job, and if she is still like this, you can’t decide anything. Just live a more arrogant life. , wait until she gets used to it before taking the initiative to come to you. If she doesn't come to you, then her behavior shows that she wants to break up, but she is using cold violence. If she doesn't get used to coming to you later, just ignore her. When she can't stand it anymore and comes to talk to you, if you have a good talk, the problem will be solved.
