Hey guys, thanks for the responses so far. I am finding it really interesting to hear what you all think.
In response to some of the posts so far:
I think I forgot to mention in this thread that I haven't been actively gaming for a while, so I didn't actually run much game on her. In fact I was struggling to remember some patterns while I was chatting to her.
The point about getting a number close is so true. I think maybe I gave off the wrong signals by just adding her to my facebook. At the time I thought it was acting laid back, but now I guess maybe it wasn't strong enough.
We chatted about all sorts of things. (A four hour convo's gotta ramble a bit! lol) We talked about family, work (boring things), I told her silly facts I learnt as routines, we teased each other a lot, compared good places to go out in the area, skimmed over previous girlfriends/boyfriends. Lots of things really.
I think the point about comfort rather than attraction could be true. As I say I have not gamed for a while and I didn't have my natural routines to hand. In the end, I suppose I really was just chatting and not really going out of my way to run game. I embedded a few good DHVs, but I missed a trick on opening opportunities for us to meet again. i.e. oh I'm going to ...... on friday, sounds good...... oh, you've never been? you should come with... lol.
I'm not sure I understand buyers remorse in this context. Unless you mean in the sense that it was a spur of the moment thing and didn't mean much in a wider context?
I'm trying to play it cool, hopefully she's doing the same. But don't worry, I'm not hung up, just seems a shame to waste what seemed like a good opening. By the way, she came and sat with me and started the convo - Damn! Maybe I've been gamed. I feel so used

lol
Anyway, your thoughts are really interesting - I'd love to hear more. What should I do now? Wait for her to reply to the message, how long should I give her before any bond is gone?
