Hello, I am new to this site and definitely seek some professional advice. A few years back i met this girl in class, she was older than me but always had a little crush. The last time I talked to her she said when I turn 18 she would go out with me. 2 weeks ago I turned 18 and by some miracle she contacted me on instagram and i got her number. After some flirting on instagram this is how our text conversation went:

Me:Princess?!?! Who do you think you are?
Her: Hey if i have to take you out to dinner I'm the man in command here hahah
Me: How about I take you to dinner and you become my older exception (she called me her "only younger exception" before)
Her: I'd love that, seriously
Me: You free this week?
Her: Not a second of free time over the weekdays but I have the weekends completely free!
Me: I can pick you up friday at 8?
Her: Awww you're gonna pick me up?!? Yeah that's perfect
Me: See you than
Her: Wanna tell me what we're doing??
Me: Probably take you to red bank (town where I live), show you off a bit, take you to dinner, and where ever the night takes us after. Does this meet your approval princess?
Her: When did you become such a sweet talker love?
Me: When did you ever give me the chance to sweet talk you?
Her: This is a good point... You're intimidating me over here!!
Me: Don't be intimidated, just making sure we're on the same page about who the "Man in command" is
Her: I'm impressed Orlando (nickname she gave me) you don't sound like an eighteen year old at all
Me: How is an eighteen year old supposed to sound?
Her: Not as smooth and charming as you do!
Me: Well you hit the jackpot, congratulations
Her: We'll see, you get an A in the via text department

conversation goes on similarly for a little bit until we both have to sleep. Out of the blue today I happened to see her at the DMV and we both came off very nervous and a little awkward and I'm terriffied that is how the whole night is going to go. I'm picking her up in an hour and any suggestions would be awesome! Thanks guys!
