Why would a guy take 1-2 days to respond?

Some context, I like this guy and at times, I feel like maybe he does too but then again I feel like he doesn’t. He will start a convo with them either by replying to a story or reel or whatever and then I respond within the same day, a reasonable amount of time if I’m not busy or faster. He’ll reply and then then he’ll reply the following day or take two days to reply. It seems like he’ll be interested in talking to me and then doesn’t rely until next day or two days from then. So, it makes me feel like: why should I waste my time? I will cut the conversation off at a certain point and not reply because I’m annoyed with it, especially since he initiates the conversation. I did this about like 3 days ago and then he responded to something I reposted like he wants a conversation and then I reply and then the next day, he replies. I’m at the point of just cutting him off completely and not talking to him anymore. I just want to know a guy’s perspective on this before I put it to rest.
