<human>: Can you give me the gist of the text in a nutshell?

So i just got a new job working on the checkouts of my local supermarket to pay my way while I'm looking for a graduate job since finishing university. About 20 other people started at the same time as me, all doing our training/shifts together, so we all got pretty close and made friends fast. The closest I've got to anyone there is a girl, let's call her E. 

We don't get much time to talk at work but it's pretty much non-stop outside of it. I give her lifts home, we text a lot, and it's progressing from there really. 

Now here's the interesting bit for me. We're both aware there's something there between us, and we've been talking steadily more and more for the past 3 weeks or so. I looked her up on facebook to add her about a week or so ago, and i was pretty weirded out when it said she was in a relationship, and had been for over a year. She'd never eluded to having a boyfriend, and had even told me she was single at one point before i looked her up. 

This kinda put me on edge a bit, because i didn't really know where to go from there. I kinda cooled it off a little with the talking because i knew it wasn't fair on this other guy flirting with his girlfriend. 

i don't think she uses facebook too much, but when i saw she'd accepted, i was pretty weirded out even more. Suddenly it said there was no relationship info to show; could mean she's either hiding her relationship from me or is newly single. 

I'm dropping her home from work tomorrow, and we've started the talking again, and we both know it could get a bit more intense, so I've got a few questions i guess. Should i confront her about this? Or just assume she's now single - and if she is, is it my fault? Can i trust her?
<bot>: started talking to a girl, found she was in a relationship that she'd hid from me but now unsure if she's still with him - where do i go from here?
