How to get him to reply back?

[SueShe]

If you want someone to reply back then you have to phrase your message in such a way that he feels obliged to reply.

You could end up the conversation with a question and that is an indicator that he must be active in order to complete the conversation.

Try to finish whatever you are saying with something like

"what do you think about it"?

This is an invitation for a reply and any normal person would reply to an open question/statement like that.

But I am not familiar with your conversations and there could be a number of reasons why a person does not take the time to reply. Have you given a thought of what the reasons could be?

Don't play texting games like that. If he doesn't reply, then he doesn't reply. Simple to be honest. I used to be annoying and try to get him to text me back. Relationships where you got to 'get him to text back', don't work.

You can't really make him.
But depends on your relationship with him, intentions, and what you sent

With a combination of black magic and Jesus you can get any guy to reply back.

Text him something funny and quirky.
