Hey fellow PUA's please help me
a little long but interesting, this story is a bit weird.

Ive Known a girl from my work HB8, after a month of knowing her, negging, flirting, DHVing, Kino, making her very angry sometimes and also laughing (emotional), and now and again coming off witty and clever, non needy, (Basically I felt i came off as perfect to this chick the exception sometimes i was a bit strange she thought) .

Anyways just before the end of last year we were at work, and i kind of let her know i might be moving to a new job next year, -with the hope she would want to sleep with me before i go(very calculating i know). One thing to note too, just over the last 2 days of working with her we just started to talk about sex, before that we had never done so.
Well it worked! Besides going limp every time i tried to fuck her (i don't think that was a problem though as we were both cool about it and i made her cum anyway)
I stayed the night at hers hugging and talking about when we first new we liked each other and why we truely said this and that leading up to it. and she was cool in the morning spooning, huggy in bed and smiley, didn't say much though?. Anyways said happy goodbyes that morning and left.
So its been 2weeks since nothing as she went to see her family back in the states, and i have not text her at all. shell be back soon.

This girl is very busy workwise so i dont think she gets much, However she is very secure, intuitive and clever.Family and friends type girl. Kinda down to earthish. Sometimes i get that feeling she really likes me (always solid eye contact and smiles over the month) however i'm still not sure if i was played. I would like to pursue this further not in the fuckbuddy sense though.
How do you think i should go about it? i don't wanna really date, that would be backward yeh? I don't have oneitis either i just want to go where i haven't before. When and how sould i text, call or facebook message?
Cheers for the help

Oh anotherthing i forgot to mention is i will actually be going back to the same work(lol), but only seeing her a couple of full days a month
