Why did he hide his Instagram stories from me?

Anonymous
I met this guy a while back and we hooked up but we both agreed that we are not anything serious. After that we only talked when we bumped into each other but never texted. Last week it was his birthday and I texted him happy birthday to which he replied “thank you my [NAME]…” and that was our communication. Today I learnt that he hide me from his Instagram stories (to which he only posts about his girl friends that’s literally The only thing he posts) and I really don’t understand why. We don’t have anything connecting us and can’t find any reason to block me from viewing the Instagram stories.
