My predecessor didn't add WeChat, but replied to the text message.

You can think of it this way. You miss him and want to be closer to him. He replied that he still has feelings for you, doesn't hate you, and is still a friend, but there are only two situations when you don't take the initiative to find you. The first is that you don't want to be near you. The second is that you keep looking for him, and he is just waiting for you to send a message. I hope I can help you. You can keep asking me questions.
