Search Results: boyfriend flirt with my girl friends

I fell hard for a girl who worked in my store about a year ago. We spent a shift together and had a lot of fun and got to talk about some interesting stuff.
I tried actively flirting with her and I had some back, even my friends commented on it. But I backed off when she told me she had a boyfriend.
But she changed after that, she seemed to take advantage of my feelings and would ask for advice, or ask for favors. But she'd also blow up on me when I'd ask something work related and would take it about her boyfriend.
Anyway after a interesting holiday season, I got a promotion at the end of December. I'd go to her store from time to time and see her, but she'd completely ignore me.
But last week, she suddenly came up to me and tried talking to me, but became really giggly and walked away. Today, she kept watching me as I walked around the store. On 4 different occasions I saw her looking at me, and when I'd look over she'd look away, but wouldn't say anything.
Is this her just wanting attention or does she actually like me?
