If you feel uncomfortable about it, then yes, you should be concerned. But if there's no negative context, it could be normal. He may just be an active viewer. Maybe he finds your stories interesting or he just likes to see what you're up to out of pure friendship. But if there's any history of him being over - interested or creepy, then it's definitely something to think about.
Well, it could be that he has a habit of watching everyone's stories and yours is just part of his routine. However, it could also indicate that he is secretly keeping tabs on you, perhaps he still has feelings for you. He might not want to directly interact with you but still wants to know what's going on in your life.
Well, it's hard to say exactly who he is just from this statement. It could be a neighbor who is just being nosy. Or it could be an acquaintance from work or school that has a bit of a curiosity about you. He might also be a family member who is checking in on you in a more modern way, through your stories.
Perhaps he is a family member who wants to keep up with your life by watching all your stories. It might be your brother or cousin, for example. They care about you and are curious about what you're up to.
This could indicate a few things. Firstly, they might be struggling to let go completely. They may be holding on to the memories and by watching your stories, they feel a bit closer to that part of their life. Secondly, it could be a form of passive communication. They're not ready to reach out directly but still want to be involved in your life in some small way. And lastly, it might just be a matter of boredom or nosiness. They have nothing better to do and seeing your stories gives them something to look at. However, without communicating with them, it's hard to know for sure.
It's hard to say for sure. Maybe he's conflicted about his feelings for you. On one hand, he might not be ready for a full-on conversation, but on the other, he still wants to keep tabs on what's going on in your life by watching your stories.
