If a person ignores him, he can still send you messages. What happened?

Maybe he really cares about you and wants to continue chatting with you. As long as you ignore him, he will always want to contact you, just some boring people. People who always want to pester you, especially those who don't want to talk to you, are even more pestering, which is particularly annoying, because they have been pestering, making it difficult for others to do anything and their minds are affected. So you still have to know what kind of person that boy is before you make a conclusion.
