I texted a boy to express my confession, but he didn't call me back. What happened?

I texted a boy to express my confession, but he didn't reply to you. Maybe they were all busy at work, so he didn't see this message. Then he will reply to you when he is finished, so you don't have to worry too much.

Also, this boy may not be interested in you, and he doesn't need to reply to your message. Because he thinks it is impossible between you two, there is no need to reply to the text message. His refusal will hurt your dignity, so it is better not to reply.

Moreover, this boy may be very introverted and don't know how to express his love to girls. Then he didn't know what to say, because he didn't reply, because he was afraid that he couldn't say it well and that the girl didn't like him.
