If you feel a bit more confident, you could leave a friendly comment on their story. Maybe something related to the content of the story. But don't go overboard and keep it light and positive. Another option is to privately message them and casually mention that you saw their story ranked first and thought it was cool. This can start a conversation in a more low - key way.
Well, it might indicate that they have a large number of followers who are very active in viewing their stories. Their followers could be really interested in what they have to share, so as soon as their story is up, it gets a lot of immediate attention, thus ranking first. It could also be that Instagram's algorithm has identified their content as something that is likely to be popular among a wide range of users.
If it really bothers you, you might consider having an open and honest conversation with them. But be careful how you approach it. Say something like 'I noticed you haven't been looking at my Insta stories lately. I hope everything is okay.' This shows that you're concerned but not accusatory.
You could just ignore it. It might be nothing more than a casual view.
You should stay calm. Reacting impulsively will only make things worse. If you love her, try to understand that it was her past. Don't let it overshadow your present relationship.
It depends on how you feel about your ex. If you have completely moved on and are indifferent, then there's no need to do anything special. But if seeing their name among the viewers makes you feel a bit of something - whether it's annoyance or a twinge of old feelings - then you need to assess what you want. If you want to cut all ties, be firm and block them from seeing your stories. If you're not sure, maybe limit what you post for a while until you figure out your emotions.
React with an open mind. Since you don't know the nature of these stories yet, it's important not to overreact. Listen to what your friend has to say. If the stories are positive and about good times, it can be a great opportunity to bond further. However, if you sense any oddness or discomfort, then you may need to have a more serious talk with your friend about boundaries and respect for your relationship.
If it makes you uncomfortable, you can block them from seeing your stories. It's your social media and you have the right to control who views your content.
You can simply ignore it. Acting like you don't notice can show that you've moved on and it doesn't bother you.
If you notice these symptoms, see a doctor right away for proper diagnosis.
You could react by simply ignoring it if you don't want to encourage any further interaction.
