Hi! I know someone who had a online/phone relationship with a guy for years...they're engaged now, so, who knows.
I would advise against trying to be flirty if that's not what comes to you naturally...who knows, maybe when you see him the first time, your knees may go a little wobbly and you'll start flirting naturally, and that's fine - but don't feel like you need to do it to show interst, or anything. You don't want his first (live) impression of you to be a false or forced one. I would just act natural, enjoy the things you can do in person that you couldn't before, and see where it takes you
