Not sure if I should keep texting? (Not responding.)

TDLR; at bottom.

I met a guy through Tinder, we really hit it off, and went on an amazing date. He actually kissed me by the end of it, and may have gone further if not for the fact that he had to go to work. We talked a bunch before the date and even talked on the phone for 2 1/2 hours, communication was great.

After the date, he suddenly became unresponsive. I could get a couple words out of him here and there, but he would generally leave me on delivered (though that’s not as bad as being left on read) and leave me wondering what was up. I brought it up briefly and he explained that he’d had a shitty sleep schedule and had been pretty busy with work, so I let it go and apologized for being uncertain.

I went on vacation with my family for 5 days and he was fairly unresponsive during the entire trip; I am returning home tonight. I’m in the car as I’m writing this, actually. He hasn’t spoken to me since 4pm yesterday, and I didn’t message him again after 8pm last night (I’d texted him three times, one in continuation to the convo, the second asking if we could call that night 2 hours after the previous text, and the third saying “psst” to see if I could catch him while he was on his phone or something. In retrospect, maybe that was excessive..)

Another thing worth mentioning: he’s leaving for a trip with his family tomorrow, but it’s for a funeral. He said he wasn’t that close with the family member that was lost, but I don’t know if he has been grieving with his family. I’m not sure.

I don’t know if I should not respond until he does, or if I should try and say something tomorrow morning or maybe even later tonight.

I’m terrified of being annoying or too persistent, so I’m not sure what to do. I’d like to not let him go since we had a really good time, but maybe that’s the message he’s been trying to put out. I’m confused.

TDLR: Do I message a guy who has been ignoring my texts for more than 24 hours again or give up? Am I overreacting?

Thanks!

UPDATE: I’m pathetic and anxious, so I messaged him. Here’s the text, will update with response once (and if) he sends one:

“I’m sorry to be a nuisance, but I’ve just been so anxious and confused for what feels like no reason. I’m really scared of being lead on, and I realize you’re going through a tough family situation, so if you need to maybe put this on pause and reach out to me maybe in a week or something that’s fine, but please don’t ignore me/ghost me”
