A man calls you and sends you text messages every day, and suddenly he doesn't call or send them. Why? What should I do if I play hard to get? He didn't look for it.

You start to get used to that person appearing in your life. Once he disappears, you will miss him very much, which means that you begin to care about him and like him. If you like him, you can tell him. If you don't like him, consider him an ordinary person. He doesn't text you, and you don't text him.
