I sent a lot of messages to a person, but she didn't reply. What does that mean?

A woman's heart is as deep as the sea. Don't worry, wait and see. If she likes you, she will be nice to you sometimes, such as smiling at you and joking with you. Then you can send her a message. If she doesn't like you, she must have ignored you for a long time, and she is very cold. Then you can give up and at least be friends. So anyway, you have to wait now, don't worry, relax and have a good attitude.
