The girl didn't reply to the message and asked her if I was bothering her. She said she wasn't. Why?

There are probably two situations. The first is that she doesn't like you and has no feelings for you. If she replies to your message, it will give you the illusion that she still cares about you. She told you that she didn't think you were bored, but she was lying and didn't want to hurt your self-esteem. Maybe there are many external reasons for you and her to make her feel that you are not suitable for being together, and often many external reasons hinder many people who are destined.

The second kind: she has a crush on you or likes you, but she just doesn't know how to face you. People who have never been in love should feel warm when someone cares so much about being cold or tired for the first time. She may want to reply to your message, but she may be too shy to reply to you. But when you asked her if she was bothering you, she immediately replied to your message. She didn't bother you. What do you mean so soon? Remove the first case, that is. . . You know

Women are very strange animals. Sometimes they don't know what they are thinking. Besides, is it someone else?
