ah well fucked that one up in a way only modern tech allows for and whilst people are saying he was needy blah blah he may have just thought he was some how scammed and decided to just quit everyone on here who has used online dating sites seem to have a plethora of scammer stories

Shit happens. Don't beat up on yourself.

If he blocked you for not being quick enough with a response in a setting as relaxed as this, how would he react in person in similar situations? While nobody wants to find out they've been summarily blocked, maybe this one was for the best.

Actually, he seems like a needy, over sensitive dick. You're likely better off.

Blocking seems harsh and may be a little temperamental. We all get busy. Shame.

Don’t worry, he obviously had an impatient streak. Could have been a lucky escape.

This online meeting thing is a whole new frontier. I'm sorry that happened to you both.
One thing I've found that is really nice is when someone breaks it down & while it seems clingy, is really great , just touching base until a freer moment, even if to collect thoughts.

But yeah, he was probably reading very hard between the lines a worst case scenario. I may be projecting but that's how I would feel. Carpe diem and all that.

Maybe he will read this post and get back to you, if not, concentrate on your trip and when you get back see if there are any others who sound like you could hit it off with. It would appear he was expecting an immediate response from you, without knowing whether you were able to do so or not. Perhaps he wasn’t the right one for you, it seems to me rather extreme to block someone so quickly and without reason.

Oops oh well don't beat yourself up too bad you're only human and we all make mistakes evidently this wasn't the right one and we all can always try to do better and be better but that certainly doesn't mean that you're a bad person just maybe a little bit overworked over stressed and forgetful

Maybe he's a bit too sensitive or reads too much into a little bit of silence, without waiting for an explanation. Or maybe he's not really available for more than a few days at a time to have a conversation with a lady. Or maybe he's got other things going on where he needs to lay low for a while and go off the site. Who knows... I wouldn't lose any sleep over it. Take care of your self first, with attention to your packing and trip.

If he reappears, perhaps you each will give each other some grace and continue with your communication if you are both okay with each other's reasons, and with better understanding of each other's lives. If not, well, let it rest and don't worry about it. You did nothing wrong. Impatience has it's consequences. Some things are worth the wait.

If he's that impatient perhaps you dodged a bullet

Sorry to hear that.
