Ex has my number or not? I don't know how to frame this?

We broke and I changed my number. He doesn't admit we ever dating or knowing me.

One morning he texted me on Insta, I asked him to call me and sent my new number. He didn't read. So I deleted my number. The very next minute, he opens the message and ring me back.

Then when I return the call asking 'who', he says wrong number. Little later when I confronted him, he said he knew it was me. He asks me to meet up. I knew he wouldn't turn up, but agreed just for the sake of it. As predicted he didn't, so I had my backup date there. He asked me to click a selfie and send it to him. I did just to stop the conversation. Again he tried to push my limits and I shouted and blocked him.

Days later I met him at a mall. we were in line together. Saw him looking at me. Get a notification that he is checking out my professional account. Then I heard him shifting the blame on me saying it was me who called the connection off to his friend when prompted to talk.

Couple days later I texted him something and he responded without even a who question.

Not sure what his intend is.

My friends tell me that this guy is not normal. His behaviour doesn't seem normal around me and his life is filled with lies and illusions. He always pretend to be cool and has grandiose.
