Short background first, been in relationship for 6 years, huge AFC, 0 game, finally got some time to game live and online.
Been talking to this girl on okc for about 10 days now, tried to set up date early on but she said she is busy with some seminar/exam thingy so she can do it afterwards. Exam was yesterday. So during that time we chatted a bit most days on okc. We also played a little game i set up, where if she guesses what do I do I will reward her with chocolate on a date (which she guessed). Today I asked for number and set it up for wednesday (so in 3 days). She tried to pick time and places where she hangs out, but i tried to make that convo short and just said I will let her know tomorrow what we will do when I set up my schedule. I am not exactly sure how to handle this (she was pretty much leading setting up a meet).
A hour and a half ago before i wrote this we texted for a while and this is how last part of convo went. Just to put things in perspective, we talked about how great would it be if we both came naked on a date, because she mentioned jokingly how it doesn't matter if she is naked in front of strangers but its awkward if she is nude in front of people she knows.
She: You know, we have been texting so long that it would actually be better if you came to my place, at least i would get a chocolate tonight!, Oh, damn, but I would have to be naked because we don't know each other

(she was referring to tonights sms texting which went on for 2 hours)
Now, I responded to this like 6 minutes later because i was on a toilet (horrible yeah)
Me: Well at least it wouldn't be awkward for other people. :3
(Like on a proper date somewhere outside. I really got caught offguard here and wasn't sure should I also invite myself to her place but she was way too quick with next answer while I was pondering that).
She: Exacly. I am going to sleep! Good night.
(she works early)
Me: Well if you didn't need to go to bed so early the chocolate would arrive

She: Hehehhe! Yeah, right, you just got brave now when I said I am going to sleep

Me: Nah, it seems to me you got scared so you quickly wrote you are going to sleep before I managed to react :3
She: Ooooh clever! I like it! Anyway good night!
Me: Night.
So, any input would be appreciated. What did I do wrong? What was good? What could be better? WHERE TO START WITH A DATE? Logistically speaking, only options for f-close are my car if i use it...or her place (she lives alone), my place is no good SPAM.
