A boy talks to me every night, but once I talked to him, he replied very slowly, once every few minutes. What happened?

First of all, the boy you are talking to may be a little interested in you and get along well with his girlfriend, but after you reply to him, he will reply very slowly, perhaps because he just has other things to delay replying to your message, or maybe he just wants to talk to you every day and doesn't want to talk too much, or maybe he just wants to get along like this to see if it is possible or think he can develop into a boyfriend and girlfriend! In view of this situation, you can try his idea in the same way. He chats with you, and you reply slowly, or not at all. Try his idea!
