A person he doesn't like sends text messages and calls every day. How to make him politely refuse without hurting his feelings?

It's actually quite simple. When he calls you, he can answer it, but it can't last more than one minute at a time. Then he can find an excuse to hang up. For example, his boyfriend calls you and so on. Use his boyfriend as an excuse. The reply message can't exceed three words. If it remains like this after a while, then his classmates will be unnecessary. Although there is nothing wrong with liking or loving a person, it is wrong to affect his life.
