After confessing to the girl I like, she didn't reply to my text messages much.

When you didn't say it before, we were still friends, and there is nothing wrong with normal chat between friends. Now that you have confessed that you are interested in her, she is not interested in you, and she is afraid of hurting you, so I am embarrassed to say it directly. If you continue to reply to your message, it will cause your illusion. So I have to keep silent.
