Well, it's a tricky situation. First of all, you should respect her feelings. Don't rush in with any grand gestures or expectations. Maybe just send her a simple message saying you hope she's okay. If you still have feelings for her, it doesn't mean it's time to jump back into a relationship right away. Give her space to heal from the divorce.
I think you need to approach it with empathy. Don't assume that just because she's divorced she wants to get back with you. She might need time alone. However, if you do want to explore the possibility of a relationship again, start by rebuilding your friendship. Listen to her when she talks about her divorce experience, and let her know that you're there for her no matter what.
It depends. If there are still unresolved feelings between you two, it could be an opportunity to reconnect. But be aware that she might be very fragile right now. So, approach gently.
Keep it private. Don't share it with others, no matter how interesting or dramatic it may seem.
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.
You could just ignore it. It might be nothing more than a casual view.
You could just ignore it. If you don't want to engage with your ex, then act like it didn't happen.
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're curious about their motives, you might consider blocking them. But if you're okay with it, you can just leave it be. Another option is to post stories that show you're happy and moved on. This might send a message that you're doing fine without them.
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 should have an open and honest conversation with her. Let her know how it makes you feel, whether it's uncomfortable or makes you question the relationship. Avoid getting angry immediately but communicate your concerns calmly.
