Just go with it Orph, you already started it, might as well enjoy it for a little while. If she does develop a thing for you, and you dont feel the same way, then break it off nice and gentle and keep on keepin on.
Just gotta point out that _I_ didn't start anything
Anyways, the core of the issue here is that she's hot (used to be a model). I don't do well with resisting hot girls. Especially when I'm drunk (a state which I usually spend way to much of my summers being in). She's nice and all that, but I don't think I can love a girl that doesn't share my interests (engineering, arguing and music mostly).
Meh. This isn't the place for pouring out all this crap. It's nice getting some tips from people that have actually experienced dating people in the workplace before, though. Though I'm used to handling women in relationships and so on, handling a situation where I've gotta meet this girl often after something like this is not something I'm accustomed to.
