@bigbanana: Feel free to adopt my motto! That’s why I share it. :-D
I wouldn’t say that I have “a lot” of dating experience! In the past 3 years I’ve only gone on 4 first dates. One I told him I wasn’t interested afterward. One I dated for about a month before I was sure we weren’t really compatible. The other two I got into relationships with, but sadly, neither of them were really ready for a serious relationship.
If you haven’t had much prior communication, that makes it harder to tell what he might have meant. I try to communicate with them before hand via email, instant messenger, text and phone conversations so I can feel fairly confident in their character before going on a first date.
I guess a brief reply leaving the door open or perhaps even suggesting another date is the way to go, if you think their is potential. You never know until you try, and you have nothing to lose!
