Does it mean anything when your ex watches your Snapchat story?

My ex watches every Snapchat story I post. I have been trying to get over him so I haven't watched any of his stories since we last spoke. I still have hope that the universe will bring us together again so I haven't been ready to unfriend him (and it also makes me happy when I see that he has watched my story).
Maybe I'm looking too much into this but is there a chance that the fact that he watches my stories means he misses me even in the slightest? If I want him to miss me should I be watching his stories? Or at least some of them?
