Hard time trying to read Pisces girl

Okay, long story short, I have interest in a Pisces girl I work with. I asked her out, got her phone number, but later found out that she was in the process seeing someone else, so backed off a little bit. Now I'm just playing the situation by ear.

Anyway, every couple of days I see her and talk to her at work. We get along quite well, but I have a difficult time reading her, even as a Scorpio. She's your typical Pisces, head in the clouds and very aloof.

Now I'm wondering, what do you all make of this. I was talking to her one day while she working and I was heading for lunch and she gets this fed up look on her face and says "I think we should quit". I said "and do what". She says "go on vacation". And it went on from there, but you get the point.

Another time we were in the break room, and I was talking to my buddy about going camping, and she says "you didn't tell me about camping!".

What I want to know is should I read more into these statements or is it just a Pisces was of building rapport in a conversation?

I have this hunch that she's at least a bit interested in me but you tell me:

- Upon 2nd or 3rd conversation with her she asked my name as I was in mid sentence like she just had to know it.
- I saw her on facebook with her phone and said "oh you've got facebook?" She said "Yeah, I think I tried looking you up but didn't know your last name".
- My aunt died recently so I told her how I was feeling and she gave me a hug and told me it would get better.

Opinions? Hey, you know us Scorps, always look before you leap!

Thanks for the comments. That's the thing though, I'm not sure what it is, if anything at all. Guess I'll have to keep my ear to the ground.
