When you broke up with your ex-boyfriend for more than a month, you still answered the phone, but you sent a message asking him questions. He said, who are you? Do you know you well?

No, he can reply to your message, which shows that he still cares about you, just wants to attract your attention or stimulate you, and let you know that you used to be a treasure, but now you are a passerby. Besides, it's been a month since we broke up. How can we forget each other's number so quickly? To ignore is to put aside the past and never meet again.
