When the earth sign does not reply to your message, the earth sign does not reply to your message.

Capricorn hasn't heard back for days. Should I keep sending it to him?

If you are a Capricorn boy, he hasn't returned your message for many days. Then I don't think you need to keep sending him messages, because you know the result, even if you send him messages for a week or two. He can't reply to you in a month or two. Since he chose not to reply to you, he certainly just doesn't want to talk to you or you. So a person who doesn't want to talk to you, what's the use of continuing to send him messages? It doesn't make any sense.
