Should I just move on?

So I've been chatting with this guy and he seemed interested (follow up with questions, responses were quicker etc) but he asked to add me on socials and then disappeared for hours before adding me back. After this, he took 3-5 hrs 'every single time' to text me back but when he does, he seems interested in the convo (his answers are elaborate, but doesn't ask follow up questions). Is he uninterested?

Should I just move on?
