First of all, when we are not very familiar with it, a boy and a girl's WeChat mainly get to know this girl through WeChat's circle of friends. There must be something in this girl that attracts this boy.

Secondly, besides that, I never send messages on my own initiative. There are three possibilities. Maybe boys have lost interest in girls, so they are embarrassed to delete friends directly, so they don't talk or send messages. It may also be that boys think girls are attractive and want to send messages to girls, but they don't know what to say, for fear that making a mistake will leave a bad impression on girls; Another possibility is still waiting to see.
