Hey there @Green_Forest
Sometimes a person not replying for a long period of time can indicate they may not reciprocate your feelings, which can feel really unfortunate. On the other hand, it may also just be that he's not great at replying quickly. If it's the latter it may be great to consider if this is a dealbreaker for you/something you may or may not be able to cope with in the future if you end up dating.
Maybe you could ask him to have a phone call with you from time to time, as that's more akin to a regular conversation in person.
If he's nice and you love to chat to him, would you consider sharing your potential feelings with him at some point in the future? Perhaps after you come to terms with what it is you're feeling, after spending some more time with him?
