Person I’m talking to suddenly taking 12-24 hours to respond🫠

So I (F24) have been talking to this guy (M26) for about 2 weeks now and overall it’s been great. We have a lot in common and last Friday he asked me out for boba. Up until then he responded rather quickly even when he was at work. The last few days he’s taken like 12-24 hours to respond. The chats themselves have remained normal. I brought up the boba date again and he said he still wants to go and asked what day works, I responded, and that was 22 hours ago 🫠

I know it’s only been 2 weeks of talking to this person, but idk if this is a big red flag, should I wait it out and see what happens, should I send a follow up text? 😅 I know sometimes no response is a response but I never know this early on 😅 Advice?
