Well, let's see. The best advice I could give you is to just be yourself and not put pressure on the situation. Of course, it's normal to be nervous---heck, I've been dating for years and first dates(I'm recently single again) are still a bit jittery, but they can be exciting. I'd say just go out & be yourself. It sounds like you know each other fairly well, so there should be plenty of topics for conversation, and just take it one day at a time. Best of luck!
