I recently went on a first date with someone I met online. We got along quite well and I agreed to a second meeting, however over the next couple of days a few things that had slightly bothered me on the date started to bother me even more and after a bit of thought I realised that this probably wasn't someone I wanted to be in a relationship with.
Because I think it would be wrong to go on the second date knowing there wasn't a future in it when he might have been hoping there was, I cancelled it. It was by e-mail which I know some people might think is a bit off, but having met online its the main way we've communicated, we'd actually never spoken on the phone. I gave polite, non personal, non insulting reasons for cancelling, apologised and wished him well.
His reply was mainly polite, but he accused me of being disingenuous! I admit, I'm a bit put out. I don't plan on replying because there would be no point, I don't plan to have any further contact with this man, but was he rude to get personal and basically insult me, or is it understandable as a response to an unexpected rejection? Was I rude to cancel an arranged date?
