What is this boy doing, help please?

[just me]

I think you should message him one more time - for example
"Hey, haven't spoken to you much recently. It's been a while, how are you?"
See if he responds to that. If he does, then see what happens. wait and see if he asks you to meet up. If he doesn't reply, he might be playing games with you - and if that's the case, you wouldn't want to be with him anyway, because he isn't worth it. I'd say give it one more shot!

If you really don't want to contact him, just carry on not responding and see how he reacts. If he really wants to talk, he knows how to get hold of you.

Good luck!
