You are not alone here. It is true that we are out of the dating thing for too long. Also it is a good thing you are nervous or have the butterfly again which is nice in a way at least in my opinion.
I am very conservation or old fashioned too, so I won't date/ meet anyone after I chatted online for a while and by the time I meet the guy I kind of know him a bit.
Same time be very careful to give out your identity or contact number.
Google online what is the best conversation for first date.
Meeting/ dating is fun and exciting simply enjoy it, but always be prepared for the worst so you don't get disappointed, as some guy will simply disappear after meeting you for the first time.
Again you also might meet a great guy too.
