Hi OP
Online dating is brutal. I think there could be several explanations here.
He might have liked you on the date and was planning on asking you out again but something happened that changed his mind ie another woman on the site contacted him and asked to meet.
He might have been undecided on the date but in case he wanted to ask you out again he tried to 'put on a good show' so that the option was there once he had thought about it
He might have sat on the train on the way home and thought bleedin heck this is actually quite a long journey. If she lived closer........but she is too far away.
He might be married/in a relationship and is bored/looking for an ego boost so it wouldn't go further with anyone
I had quite a few dates where I thought they had gone okay and then got feedback which surprised me.
One said I was really 'aloof' on the date when I thought I had been nice and normal and listening to him as he was chatty. He did ask me out again but took to the wednesday from a sunday date. I didn't hear from him in between those days. This was slow, most asked me out within a day if they were going to.
One I went out with twice and after the 2nd date he didn't attempt to kiss me. I know from something he said after our first date that he was quite taken with me so not sure why he didn't try to move things forward. He popped back up a few months later saying his mum had got ill and he had been sorting out a care home for her. I just said sorry to hear that but I'm dating someone else now (I was). What the real story was I will never know.
On the other side I have been on dates where I have gone home and deleted my whole profile to stop them contacting me again. So I guess that would be considered rude as he had no way to contact me. I actually just felt a bit interogated and vunerable on the date and went into panic mode I think.
Another insisted on walking me back to my car (in the middle of the day) but didn't hug/kiss me and I never heard from him again. (I didn't want to go out with him either so perhaps he picked up on that or perhaps we just didn't like each other)
Another guy I went on a 2nd date with and I didn't like his aftershave. I know that sounds weird but smell is important. Then the date went quite well in terms of chatting etc but I offered to pay half (he had invited me to dinner) and he said okay and let me pay half. This really put me off him which I'm not sure if I was unfair or not. I mean he was maybe taking me at my word that I wanted to pay half or perhaps he was just a tight wad. I would have paid for the next date but for some reason this just put me off him. No money was spent by either on the first date. So I text him after to say I wasn't over my ex and was going to take a longer break from dating.
Another guy I met for coffee and thought it went okay but I accidently was a bit 'bitchy' about someone. Not my usual style at all so it was probably nerves. He send some chatty texts after the date and we text back and forward that evening. Then never heard from him again. So not sure - was he waiting for me to ask him out.
Another guy met for a drink, he asked me to go for dinner so I said yes as it was still early. He then proceeded to get drunk and tell me all his problems so I felt quite uncomfortable. Later after the date I thought about it and thought I had enjoyed the date up to that point so decided maybe he was nervous and drunk too much and was seriously regretting it. So I decided to ask him out again and he made a big deal of telling me he smoked pot, watched porn and something else (I think he thought I was too much of a 'good girl' for him. I made a joke and said 'oh so you're a normal bloke then' and then he did say he thought we should go out again but by this time he had put me off him and so I didn't reply.
Anyway the point of this long post is to show you a female side of dating and how some of my behaviour could have been seen as 'bad' by the man. Mostly it was just me with my own insecurities, worries, trying to work it out.
I used to think it was rude to not text someone but now I just think they are giving you an answer (no) but just in an indirect way. So i think you just need to accept that no response is a negative response.
I definately would not text him again. I'm pretty sure he will pop back up at some point in the future and then of course it's up to you what you decide to do.
Good luck. I stopped dating 11 years ago to concentrate on other things. I am considering going back to it but as I'm now older and less attractive I'm just not sure if I can cope with all the negative that comes with it.
Good luck. None of us like rejection.
