<human>: I have got a crush on a co-worker. She is pretty, smart, well educated(better than me anyways), extremely trustworthy and I feel less socially anxious when I'm around her, i.e. she has a very positive influence on me. 

I have known her for about one and a half year, however, we work shifts, wich means I've seen her maybe 14 times over that period of time. She does her studies abroad, and works when she is home. 

I am extremely bad at giving signs/flirting, but not as bad as I am at reading them. However, the other day we went out and grabbed some after-work beers. There was some unneccecary touching from her side, wich if I'm correct, is a womans way of showing some interest. Also, when she hugs me it's the full-body, both arms around the neck hugs.

The problem is she is the kind of girl who is "one of the guys", so it may just be I'm reading all these signs wrong. And if I make a move, the friendship may be over, and if we get paired on shifts, it can make for some really awkward shifts. 

She is going away for a year to study(wich means it's possible to let this blow over if I mess it up), but wanted to join me in Thailand over christmas holiday, and had me install something called "viber" to stay in touch.

Instead of idling trying to read her signs, I figured I would ask you guys for a) is it worth the risk? and more importanly b) how do I signal an interest in her without neccecarily ... signal an interrest. I feel like I have my legs in two different camps. On the plus side, this is a temporary job for both of us, on the negative side, she wanted to move halfway across the globe to open a diving shop together(wich I'm guessing is out the window if I make a move and she shoots it down).

Summarize the given text in a few sentences.
<bot>: I am interested in a co-worked, and I think she might be the same. Is it worth the risk to move forward, and if so, how do I proceed?
