What do I do when I meet a girl for the first time after talking to her for 3 years?

SO basically I've been talking to this girl Madison for 3 years. I met her sadly on an iPhone chat app 3 years ago & oddly enough we really hit it off. We would Skype every night for at least 4 hours at a time (Keep in mind she's living in Colorado for the first 2 years) Those first 2 years we we're really into each other & things almost seemed perfect & if we were to meet it would be the greatest thing ever. But the last year we lost contact & things seem different. I messaged her on Facebook last week with a long meaningful message asking if she would like to meet me for the first time cause it would mean a lot to me, with her long response it seems like she still cares for me, well she ended up saying yes, which made me tear up a bit cause i really do care for this girl cause now we're only and hour & a half away from each other cause we're both going to school in Texas but I don't know if her feelings are still the same as they used to and I was wondering what exactly I should do from the start to not only see if she still likes me like she used to but also to see if she'll want to see me again cause I obviously would like to see her more than once being that we're pretty close to each other now.

Any Ideas would be appreciated. Just don't be a d-bag with your answer.

Do what you've promised her in those daily hours of chat for years

Sounds like a really good friendship. You'll do fine just be yourself. You wouldn't want to act like someone else then get her thinking that is how you are.
