What does it mean that people who don't love you say nothing is useless?

It's useless for people who don't love you to say anything, just like you can never wake people who pretend to sleep. He's pretending. How can you keep him from waking up? He obviously doesn't love you. No matter what you say or do, he turns a blind eye and turns a deaf ear. Because he doesn't love you, he doesn't care. Don't put your heart and heart on such a person, because there is no result.
