I chased a girl and sent her a good night message every night.

Maybe you don't feel anything when you send it to her every day. Try not to send it for a few days. She got used to you sending messages every day and suddenly stopped sending them. Of course, she wants you to send it. A short message won't bother her. She will feel that people in this world care about her every day, but they are not the people she likes, so she doesn't care. If she likes it, she can chase it bravely. She can say whatever she likes. Confession is the fastest way, no matter what.
