I'm new to this. I went on my first POF meeting/date.
We met for a walk in the park during the day. It was fine, conversation was fairly easy. Nice, friendly person. Enjoyable enough walk. I don't really feel any need to see the guy again. Nor did I get the impression he was interested in me beyond the one meeting we had. The signals I got were: at one point, I asked if he wanted to keep going or turn around, and he said "let's turn around here" plus instead of walking all the way back to our meeting spot, he stopped walking and indicated he was going to turn off at an earlier street so he could do some errands - whereas I could have gone either way - walk together longer, or not...but I took that as a sign that he wasn't all that interested either. So it's all good, and I'm sure it goes that way most of the time.
I thought it'd be polite of me to send a quick message to say, "thanks for an enjoyable walk today" or something to that effect, but I fear the etiquette of on-line dating is quite different and I don't want it to be construed as looking for another get together. So do I say, "Thanks for the walk; nice to meet you. I don't think it was a match but good luck in your search" as I've heard other people do if the other person asks about a second meeting. Is this even necessary or is no message of acknowledgement needed if you don't want to get together again? What if I said, "Thanks for an enjoyable walk! I didn't think we were a match and I got the feeling you didn't either, but it was great to meet you and chat, and good luck with your search." Or is that unnecessarily blunt and presumptuous, in that no message at all would also convey that we weren't a match?
