It could be that he doesn't have enough time to watch stories. Stories disappear after a while, and if he's busy, he might only have time to like the more permanent posts. Also, he might be more interested in the topics you cover in your posts rather than the more spontaneous and often more personal content in stories.

He could be really busy. If he has a lot on his plate, he might not have the time to check out your stories. For example, he could be swamped with work, schoolwork, or other personal matters.
It could be that he's not really interested in that kind of content or doesn't think it's relevant to him. Or perhaps he didn't even notice that you shared the stories.
