I have been catching up with this thread and cheering on those of you who have had good experiences and sending virtual hugs to those of you who have not been having such a good time. Too many people to name individually, so sorry for being a bit 'sweeping' with my post.
Kerkyra I agree with Batshit that you should go back to him saying it was nice to meet him but feel that there was no chemistry and wish him luck in finding someone.
Please don't put yourself down or compromise on your needs - it can be tough finding the right person but better to be single than dating someone who you don't really fancy and/or have nothing in common with. I have been known to have a second date with someone out of sympathy and trust me, it is shit. Far better to end things politely now than drag them out. You won't feel any differently about him after a second date, trust me. And he will have been given false hope.
On a personal note, I am feeling very positive about Mr Outdoors and looking forward to seeing him on Thursday evening. He seems to be a genuinely nice guy and the chemistry is definitely there. It is a shame that he lives an hour's drive away from me (down scary winding country roads!) as I am not a big fan of driving long distances in rural areas, but I am putting that aside for now. I have been half-heartedly messaging a few other irons but I haven't even thought about giving them names and have not arranged to meet anyone else.
