UPDATE:
Yesterday(monday) I told her that the date was going to happen today. She was busy at work till 21:00, but she suggested we meet up this weekend - which I agreed to. We agreed on sunday around 15:00.
This means that I have to maintain some sort of text game for 4 days, as I won't be seeing her till sunday.
So far my strategy has been to maintain my frame as the FUN guy, who makes her laugh by giving her small challenge this sunday, and framing me and her with silly names in a silly story.
I am trying to respond as slow as possibly without seeming too aloof, and to save myself from sending too many texts.
But I fear that I quickly losing topics and ideas for how to keep the conversation alive. So far, she has sent me good IOI's as in; "I'm going to charm you till you melt!

". My response to this was; "I better hope you'll give me a kiss to return me to my former form!

" and she said; "Haha, you'd like that!". She wants me to give her a massage as that would "make her happy", she says. Additionally she wants me to drop by her work, when there aren't many people, with some candy and hang out while she is at work.
Ultimately, its going OK, in my opinion. Not too bad, but not perfect either. Plenty of interest from her side.
Just two hours ago, she wrote me goodnight, in which I responded, and she kept answering back and forth for 20 mins, until i finally said; "Time for you to go to bed, silly!

Sleep tight! You're responsible for writing me a good morning message tomorrow seeing as you kept me awake!

haha". Her response was; "I am going to bed now (sleeping emoticon) Good night!"
So I got two questions where one of these might sound a little silly - but pardon me, text gaming is my weakest point.
1. In case she doesn't write "good morning", how should I proceed? My plan was not to write her a message at all tomorrow if she doesn't do this, but will it have a negative impact? And what other options do I have in case she doesn't write me? (Yeah, I know - silly!)
2. How should I steer this text conversation on facebook? Got any quick tips? I'm more of a face to face person, as that is how I do my best gaming. But seeing as how I have suffice with text gaming for 4 days, I would greatly appreciate help on this as well!
My thinking was perhaps making her play a game of "Either" in our conversation. Could be a fun way to get to know each other and I might even build some sexual attraction this way.
Whats your point of view guys?
