Guy's Behavior

What does it mean when a guy that used to look at all of my Instagram stories and react to them, suddenly stop watching my stories completely?

He still likes my Instagram posts, but no longer watches my stories at all. I think he put me on mute, but I am unsure why because I barely know him and I never said or did anything that was rude or mean towards him. I was always kind and inviting.
