There's also a possibility that there's an issue with the app or his device. Maybe the app isn't notifying him properly about your stories, or his device has some glitches that prevent him from seeing them. Also, he could be intentionally avoiding your stories if there has been some sort of disagreement or awkwardness between you two.
Maybe he's just busy. He might have a lot of things to do at the moment, like work or study, and simply doesn't have time to check your stories.
Maybe he's just not interested in that type of content. Everyone has different preferences when it comes to stories.
Maybe he's just curious about your life. People often check out others' stories to get a glimpse of what they're up to.

It could also be that something in the story made him uncomfortable. For example, if the story contained topics that he didn't like or disagreed with, he would choose to stop watching it. Also, perhaps he accidentally clicked away and then just forgot to come back to it. There are many possible reasons for this situation.
He might be bored and your stories are a source of amusement.
Perhaps there's something going on in his life that's causing him to be distracted or not in the right mindset to watch your stories. Maybe he's dealing with personal issues or stress.
Maybe he's just lurking and not in the mood to text right now. Sometimes people enjoy seeing what others are up to without feeling the need to communicate.
Well, there could be various reasons. Maybe he's got some personal issues on his mind and doesn't have the mental space for your stories. Or it might be that he's trying to distance himself for a while for no particular reason. It's hard to say for sure without knowing more about the situation.
