accidentally ghosted? (pls help)

so I’ve been talking to a mutual friend of mine for a little over a month. conversations have been going great once we get past his habitual “wyd” and dry texts, we have a lot in common, and we’ve met up for one date. well a week ago he left me on a very dry text (“lol ya”) and at the time, I wasn’t in the mood to respond/spark up a new topic. I meant to answer back but I got side tracked and 3 days went by. besides my bestfriends, he’s the only person I had consistently texted everyday up until that point. I realized that I had accidentally ghosted so I hit him back up apologizing and trying to start up a new convo, but he hasn’t responded back and it’s been 4 days. and he’s been posting on his social media in the mean time. I genuinely feel bad. Idk whether he’s intentionally trying to take twice as long to text back or if he’s called it quits and using this as his “way out” 😕

how should I approach this?
