What does it mean if guy becomes less active on instagram after I started to ignore his posts/updates there?

I’ve suspected that he liked me since he used to check me out in public and based on our very friendly conversations in the instagram dms.

I always initiated texts and he very rarely messaged me first so I started to miss his story updates and not like his pics. Now I noticed that he’s been less active on instagram
compared to normally.
