I sent her a message, and she replied at first, and then repeated it several times.

I started to reply, but I didn't reply much later, which means I don't really want to chat with you.

First of all, if a girl has a crush on you, she will definitely reply to every message you send, even if some of them don't reply at the first time because of something, they will reply in their spare time.

Secondly, some things you send should be boring, maybe just trivial things, and girls don't like to take reason.

Finally, try not to send messages. Making phone calls or voice calls are good choices. If others see the news and don't reply to you, you will think twice. If you refuse to answer the phone directly, don't think about it.

In short, if girls are not interested in you, don't be too active, it doesn't make much sense, and winning over is also a spare tire.
