Ex playing mind games?

Okay long story short my ex broke up with me 3 months ago. Our relationship was brilliant at the start but then the smallest disagreement would get blown out of proportion by him and he would end things. Then he would chase me and want me back.
Recently he has been stalking my instagram and messaging my friend whenever he has seen me on their snap story (he never goes out of his way to message my friend any other time). He has me removed from all his social media, removed me as a friend on snap and the other day he made his story public, so it showed up on my snapchat. He did this the first time we broke up too, and later admitted he was trying to see if I would watch his stories. I gave in to temptation and watched his story and then he blocked me 20 minutes later. He has now unblocked me 2 days later and is back to posting public stories. Can someone please tell me what he is trying to do right now? Is he trying to get my attention or what? Very confused right now haha
