he didn't watch my snap story

There's a chance he's not interested in the content you usually post. If your stories are mainly about things he doesn't care for, like a particular type of fashion that he has no interest in, he might skip it.

Well, it depends. If this is a one - time thing, then there's no need to worry. But if he consistently ignores your stories and other forms of communication, then it might be a sign that something is off in your relationship. However, just based on him not watching one snap story, it's too early to be overly concerned.

Perhaps he has some sort of issue with you, although it's not very likely just based on this one instance. But if there has been some tension or misunderstanding between you two recently, it might have influenced his decision not to watch your story. For example, if you had an argument and he's still a bit miffed, he might be avoiding any form of engagement with your content for the time being.

You could just let it go. It might not be that big of a deal. Maybe he'll see your next one.

Maybe they're just too busy or not in the mood to check snaps at that moment.

Maybe she was just too busy at that time. There could be a lot of things on her plate, like work, study or taking care of family. So she might not have had the time to check your story.

Maybe they are just too busy. They might have a lot of things going on in their life like work, study or personal chores that they don't have time to check Snapchat. Another reason could be that they are not really into Snapchat stories in general. Some people prefer other forms of social media interaction.

Maybe there's a glitch in the app. Sometimes technical issues can prevent you from seeing the stories even if you haven't been blocked.

It could be that your internet connection is unstable, preventing the deletion process from going through properly. Or, there might be some settings you haven't configured correctly.

It could be that they've unfollowed you without you realizing. Sometimes people do this to create more distance after a relationship ends. Or they might be so focused on their own life now that they simply don't have the time or interest to check out your snap stories. They could be busy with work, new hobbies, or building new friendships.
