Why is my ex situationship ship still viewing my stories?

We haven't talked in over a year, I may sound delusional but just stick with me; He started 'secretly' watching my stories from late march from his fake account as of still doing it now in November: 8/10 for him to watch them to be more specific if that makes any sense. Ugh I don't understand you men. I know it's his finsta account but yet don't know why and again why for so long? He has never reached out to me since we stopped talking.
