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.
There could be a bunch of reasons. Maybe he's jealous or doesn't think they're interesting. Or perhaps there's a misunderstanding between you two that's causing him to act this way.
Maybe he's not interested in the content of your stories. Some people have specific interests and if your stories don't align with them, they might not bother to watch.
You could try to engage with her in other ways. Maybe start a conversation about something else that interests both of you. This shows that you're not overly focused on her not watching your stories and gives you a chance to build a better connection. Another option is to privately ask her if there's a reason she doesn't watch your stories. But be prepared for an honest answer that might not be what you want to hear.
