If a girl secretly loves me, but sends her a message, sometimes she replies and sometimes she doesn't reply, what does it mean?

First of all, you should make sure that this girl really likes you. What if you really like it? If you send her a message, she will definitely send you a message, as long as there is no problem. As for us, we can't rule out the girl's work. It may be delayed sometimes, so I'll give you a few messages. Besides, it is impossible to leave you messages instead of doing work. So, if this girl has a good impression on you, it doesn't mean that there are no messages here. Will change you. What about this girl? I think so, too. What about you? I still have a good impression. What if I don't? He won't return your message.
