Boyfriend used to like to send WeChat and chat in space. What does it mean to be quiet after breaking up?

It just means that he loved you very much before he broke up with you, and he will be the same after he broke up with you. As for him, it's just a form of self-paralysis. He doesn't want you to know everything about him. He wants to disappear immediately, but he doesn't want to delete you, because this is probably the only tool to know and understand you in the future. After all, mobile phones can't be dismantled.
