If it really bothers you, you could try sending him a friendly and non - pushy message to see if he'll start a conversation.
Perhaps she doesn't know what to say in response. Watching your stories is her way of staying updated on your life without having to come up with a reply. It could also be that she doesn't want to engage in a conversation directly but still wants to be part of your world through your stories.

Perhaps he's a bit shy or nervous about texting back. By watching your stories, he can stay updated on your life in a more passive way. It's possible that he doesn't feel confident enough to start a proper text conversation, but he still wants to know what's going on with you.
Maybe he's just casually interested in your stories without wanting to fully follow you. He might not want to seem too eager or committed by following.
There's a possibility that he's just casually browsing. He might not follow a lot of people but still checks out interesting stories when they pop up. Another reason could be that he doesn't want to be inundated with all of your posts in his feed if he were to follow you, but likes the quick and ephemeral nature of stories.
