If you tell a boy to respect his choice, isn't it bad to send him a message when he doesn't return?

If you tell a boy to respect his choice, it is not good to send him a message if he doesn't return. I told him I respected his choice, but he didn't reply, which means he acquiesced in your answer and didn't want to contact you again. I hope you can understand what he means. So if you send him a message again, it will make him fall into the awkward choice of replying or not, and at the same time you will doubt whether he will reply to the message, which will make both of them uncomfortable. So it's not good to send messages again.
