I was just wondering if there's a reason?' This can open up a dialogue. You can also consider sharing your stories privately with them for a while to see if they respond. If they do, it might mean they just prefer private interactions over public stories.
It could be that they've unfollowed you without you realizing. Sometimes people do this to create more distance after a relationship ends.
