Perhaps you should focus on moving on yourself. Don't let her actions of watching your stories disrupt your own healing process. If she wants to get in touch or has something to say, she'll make the first move. For now, keep living your life and don't let this small thing consume your thoughts.
You could try reaching out to her in a friendly way and ask her why she's still watching your stories. But be prepared for any kind of answer, including a cold one. Maybe she'll be honest and tell you that she misses you a bit, or she might just say it's out of habit.
No, you don't need to be worried. It's probably just his way of staying updated on your life out of simple curiosity. He may not have any malicious intent.
She might be simply nosy. Just because she ended the relationship doesn't mean she doesn't want to know what's going on in your world. It could be that she has a habit of looking at people's stories and yours is just one of them.
You could try to respect her decision to block you and just continue living your life. If she's interested in your stories, she might come around on her own. Don't push the situation by trying to contact her through other means.
It depends on how you feel. If seeing his name pop up as a viewer makes you uncomfortable or prevents you from moving on, then yes, blocking him might be a good idea.
I wouldn't be too hopeful. Just because she watches your stories doesn't mean she wants to get back together. It could be a simple act of curiosity.
It could mean he still has some level of curiosity or he's not fully over you. Maybe he misses the connection you had and watching your stories is a way to keep a small link to your life without actually getting back together.
It depends on how you feel. If it's bothering you a lot, then you could confront him. But be prepared for any kind of reaction. He might deny it or get defensive.
I don't think so. Since she has already rejected you, approaching her might make her feel uncomfortable.
It depends on how you feel. If you still have feelings for her, you could try sending her a casual message related to one of your stories. But if you're over her, you can just ignore it.
You could react by simply ignoring it if you don't want to encourage any further interaction.
