Mercury,
As usual I will attempt to be completely frank with you without being rude

. From the tone of your post, I am suddenly reminiscent of 10th grade dating situations on both of your parts..."connections"...pulling strings...talking to everyone she/you knows...
I really don't think she would even care enough to give a hoot what you think if she didn't really like you, at least as a cherished friend. To tell you the truth, after re-reading the post, I don't even see HOW you have any ground to stand on to be angry at her, besides that it really would have been nice to hear from her.
I don't even see any evidence of so-called "games that people play". Maybe I'm missing something but - what games exactly? Personally, if I were her, and you gave me a nonchalant attitude about it after I hunted you down and honestly explained the situation, I'd never call you again just for that. The woman is a single mother with a busy career...she is obviously not cruel because she would rather be honest and say she is too busy, instead of hooking you in and dragging you along, all the while never having time for you.
Tons of women nowadays wouldn't even have bothered to call you, much less call to thank for the flowers or attempt to set your mind at rest. I sincerely think you are overreacting due to your past experiences, and this is exactly what always ruins it for people. However, it would also be unwise to jump headfirst into this situation, which I take it was your problem in the past.
Why don't you aim for the HAPPY MEDIUM

Somewhat trusting, yet cautious...i.e. see if she calls, and go out on a date again...
EDIT:
I also agree with Mr. 5.0; My fiancee and myself have been together a short time, but we spend ALL the time either together, on the phone or on the net talking. I also do see why the disappearing act is weird. REGARDLESS...barring the fact that she didn't call, vanishing like that in general is just creepy and suspicious...I just don't think you should really expect that much at this point of the relationship. Seems like you might have been a little more serious than she was (take it from someone who gets attached REAL quick

)
Like 5.0 said; just take it slow and give things a chance. Either they will work out - or they won't.
Female Manipulation?

I think its human manipulation...both sexes have guilty specimens...
