A blind date met a girl and added her WeChat. She never sent me a message on her own initiative. Is it because people are not interested in me?

If you meet a girl on a blind date, but she hasn't sent you a message since you added her WeChat, then I think for girls, it is generally very much hoped that boys can take the initiative to find her, which will make girls feel more important to boys. In this case, he didn't take the initiative to send you a message, in fact, he thought so. It's not that he's not interested in you. He just wants you to find him.
