Not everything is black and white. Some people would say give the person a chance and talk to them, get to know them and maybe their personality will win you over. Some people like yourself, would say " you should have either not replied to his first message, or politely said that you are not interested." But as you said though, it's just your opinion. This is why I said there's no pleasing some people.
Some people really need to stop getting so wound up over internet dating..
I'm not getting wound up lol I was just a little shocked at other peoples atitude towards dating websites.
I know things aren't clear cut, I agree, give somebody a chance by chatting first, but the scenario I interpreted from your posts was that you had chatted for a good length of time, so much so that a date had been arranged, then you changed your mind because you had doubts...That's why I said no you shouldn't have talked to him any more and told him you weren't interested from the first time you had any doubts.
