she keeps watching my stories

No, not necessarily. It could be a positive sign. As I said before, she might be interested in you or just being friendly.

It could mean she's interested in you. Maybe she likes you and wants to know more about your life through your stories.

It could mean that your ex is still interested in your life. Maybe they miss you or are just curious about what you're up to these days.

It could mean a few things. Maybe they're still curious about your life or they haven't fully moved on. It might also be a habit they haven't broken yet.

It may be that they're still interested in your life to some extent. They might not be able to completely cut off that connection and seeing your stories gives them a little peek into your world.

No, not necessarily. As I said before, it could just be out of curiosity or he might find your content interesting.

It might mean he's interested in you. Maybe he likes you and wants to know more about your life through your stories.
