What does it mean for a woman to say don't send me messages often if she has nothing to do?

What does it mean when a woman says it's okay, don't send me messages often?

The meaning is obvious. I really don't want to chat with you, which means I have no interest in you, but I don't hate you.

You may talk a lot recently, and she may feel that she has no time to do anything else. Chatting takes up too much time, she will say don't send her messages often, she needs to rest! This is her guess that she doesn't like you!

If the average girl is interested in this person, she will not refuse to chat. Even if you send her messages all day, even if she is busy, she will take the time to reply to you. Maybe when you don't send a message, she will take the initiative to chat with you. But if a girl hates you, she won't want to talk to you at all. Even if she chats, it is a polite and simple reply. Most of the replies are in one sentence, and ten replies are a face.

In your case, this girl doesn't hate you and is willing to chat with you, but she has no other thoughts about you and just wants to be an ordinary friend, so she doesn't want to spend a lot of energy and time chatting with you, but if she doesn't reply to your message, she will feel guilty again, so she can only choose to tell you clearly that she wants to keep in touch but doesn't chat every day.
