What's her deal?

Ok this might be long so bear with me. I Work at a grocery distribution factory been there about 3 months now. There's this girl lets call her K. K works in my department but in a different division than i do but certain tasks we work together. The first time i ever met K she knew quite alot about me. She knew my name and small stuff. We chatted and parted ways. The next time i encountered her she was getting off the 2nd floor ( i work on 3rd floor). I was chatting with a couple of coworkers and she randomly just stops turns back and says "It was nice to meet you the other day C'. I nodded my head smiled and went to my quarters.

Not too long ago i had to work on her floor for a couple hours. She noticed me walked up and started talking. Asking questions and most importantly asking if i was in a relationship. I said no and asked who wants to know? She answered it was just a normal "adult" question. Out of maybe like 40 girls at work she was the first one to ask me this. I proceed to ask her to add me on facebook which she did rather quickly.

After i added her i told her in at work that her kids were handsome cute what not. That following evening she posts i swear i have the cutest kids ever. Couple days later i change my profile pic and not even 2 hours later she does the same. I liked her pic and logged off. The next day she was showing up in places i would never see her before. In the break room tables are surrounded by our lockers. She started to sit wiht her friends in front of my locker. I would go to the bathroom and come out sure enough shes standing there with her friends. Everywhere i go i seem to "run" into her but she doesnt say anything to me. From coming back to lunch to standing beside me during stretches and meetings.

I actually built up the nerve the other day to ask her to do something over the weekend But thursday morning i get on facebook and she updated her relationship status to in a relationship with what most definitely is a fake account. My question is what is this girls deal? Is she interested? Is she trying to make me jealous? Is she shy? Any input will help.
