<human>: Hey reddit
I've been thinking about this for days. I could use your help. 

There's a new girl at work. We're on different floors so I don't get to see her much but when I do, we always chat for a good while and we're both interested in spending time outside of work (I've casually said that we should go out sometime and she agreed on a few occasions. The other day, she asked if I was going out to the bars as she wanted to, but unfortunately, I had prior plans). 

We had a chance to chat again the other day before our holiday break and towards the end of our conversation, she shyly/awkwardly said that she was "kind of seeing someone..." but she's not sure if this will last until after christmas break. This is where I'm lost. 

Can reddit help figure out why she said that? Was that a kind way of her saying "I'm with someone, leave me alone?" If she's truly interested in me, why would she have even brought that up? 

When we first met, she was the one that first initiated the conversation and always asks meaningful/personal questions that most "acquaintances" wouldn't ask.

Could you distill the essence of the text into 1-3 sentences?
