In most cases, no. People watch stories for all sorts of reasons. Just because it's your ex's friend doesn't automatically mean something bad. However, if their viewing makes you uncomfortable, you could always adjust your privacy settings so they can't see your stories. But if you're fine with it, it's probably nothing to worry about. There's a good chance they're just being nosy or curious in a harmless way.
Well, it could simply be that they find your stories interesting in their own right. They don't necessarily have any ulterior motives. They could be the type of person who likes to watch a variety of people's stories, and yours happened to catch their eye. However, it's also possible that they are still in touch with your ex and are doing it as a sort of loyalty thing to your ex, to see if you're saying anything about them.
It could be that they still have some interest in your life or want to keep tabs on you for various reasons. Maybe they think you have something interesting to share or it's just a random act.
Not necessarily. If it makes you uncomfortable, you can always limit their access. But it might just be a harmless thing on their part, like casual curiosity.
It could mean a lot of things. Maybe they're still curious about your life. Or perhaps they miss you on some level and this is their way of staying connected without actually reaching out.
It depends on your current state of mind and your relationship with your ex. If you're in a new relationship, it might be a bit concerning as it could potentially cause some jealousy or insecurity. But generally, it's just their way of staying updated about you, and it doesn't always imply something negative. If it bothers you, you can block them or limit their access to your stories.
It could mean a few things. Maybe they're still curious about your life. Or perhaps they miss you a little bit and this is their way of staying somewhat connected without actually reaching out.
