What do girls mean by sending three short messages?

Because you are just boyfriend and girlfriend, it is possible that your feelings are not particularly strong, so there was a quarrel and three messages were not sent again. That's because your boyfriend doesn't love you very much. If he really loves someone, he will come to you and explain it to you clearly. If it is your fault, he will admit that it is his fault to make you happy.

So I sent you three messages about your quarrel with your boyfriend after the cold war, and you didn't reply to him. Maybe he thought the quarrel was your fault and apologized to you, but you didn't reply to him. He felt embarrassed! Maybe after careful consideration, he thinks you are not suitable and gives up!

It's just that I think if you really love him and this quarrel is your fault, you can also send him a message, saying that you didn't see the message he sent, because the mobile phone is broken and it's only now repaired. You can also say so, see what he says!
