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 it bothers you, you could block them. This sends a clear message that you don't want them involved in your life, at least in this way. Or you could also make your stories private so they can't view them anymore.
It depends on how you feel about your ex. If you're over them and don't mind, then there's no need to do anything. But if it stirs up old emotions or makes you uncomfortable, you might want to take some action. You could also send them a polite message asking them to stop if you think they'll respect your request. However, this might reopen communication which you may or may not want. Another option is to start posting more positive and independent - looking stories to show them that you're doing great without them.
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.
Not necessarily. It could just be casual curiosity. Don't overthink it unless you notice other signs that she's trying to interfere in your life.
It depends on how you feel. If it makes you uncomfortable, then yes, you can block them. You don't need to put up with something that bothers you.
If you're comfortable, you might send a polite but firm message asking them to stop if it makes you feel uneasy. However, if you think there could be a chance of friendship in the future, you could reach out and have an open conversation about why they are so interested in your stories. It all depends on how you feel about your ex and what kind of relationship you want to have (or not have) with them in the future.
You can start by following him back if you're interested in him too. Or you could send him a direct message if you feel comfortable.
If it really bothers you, you could try reaching out in a non - aggressive way, like sending a simple text asking how they are. But be prepared for any kind of response or no response at all. For example, 'Hey, I noticed you stopped watching my stories. Just wanted to check if you're okay.' However, this might reopen old wounds or create more confusion.
Just ignore it. Maybe they're just being nosy or still have some interest, but you don't have to let it affect you.
You could just ignore it. It might be nothing more than a casual view.
It depends. If you're over the relationship and have no intention of getting back together, then there's no real need to worry. But if it makes you uncomfortable or you think they might be trying to stir up old feelings, then it could be a bit concerning. However, don't jump to conclusions right away. They might just be passing the time by looking at 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.
