Why did my ex stop watching stories all of a sudden?

It could be that they heard something about you from mutual friends and are now curious to see if it's true by watching your stories. For instance, if a mutual friend mentioned you got a new pet, they might look at your stories to confirm it. They're avoidant, so instead of asking directly, they choose this more indirect way.

It could be that they don't have the time or maybe they don't want to think about the past and seeing your stories reminds them. Another possibility is that they have new things going on in their life and have less focus on social media in general.

Maybe they just lost interest or are too busy with their own life.

Maybe they still have some interest in your life or just happened to come across them by chance.

Maybe they're just busy or not in the mood for social media lately.

Well, maybe I just got too busy lately. There are so many things going on in my life right now, like work and other personal stuff, that I don't have as much time to check out stories as before.

Maybe he lost interest. People's interests can change over time. He might have found other things more engaging or he could be busy with his own life and doesn't have time to keep up with your stories anymore.

Maybe he was just too busy and didn't have the time.

Perhaps she had some personal issues or distractions that prevented her from giving your stories the attention they deserve. It might not have anything to do with you or your stories specifically.

Maybe she's just too busy and doesn't have the time right now.
