A girl I met on the internet is coming to my home town(she lives 45 mins away)?

Don't put too much stress on it. She will be able to pick up your nervousness and it might also make her nervous. Just be yourself. If she lives 45 minutes away, she probably doesn't know your town very well. Take her to a park, a museum, on a walk, etc. If that's not your thing, maybe a movie, dinner, lunch, or maybe even some type of amusement park or something. She obviously likes you, for your personality, or whatever, just be yourself. Do things that you would normally do with friends, and make sure you introduce her to your friends and maybe have them help you think of stuff to do.
