Is she playing games or just a weirdo?

[yabby]

Intitally she kept looking at me, creepily kind, walking infront of me to get my attention, acting more shy timid around me. by the way she is is not a shy girl.

-Talked to her she was nervous whatever we introduced ourselves, because things were getting very creepy and i had to put and end to it. I found out shes a okay person

-Then I talked to her again she was nervous again, i thought she was cool, then i asked her for her number, she said you can add me on facebook but didn't give me her number. She rejected me but whatever i dont care.

- i added her on facebook 2 weeks later found out she is in a relationship, totally weird.

-Met her again talked to hershe was nervous again moving her feet like ants in her pants, I finally asked her why she was nervous she denied it, and then stood closer to me while working acting shy/quiet to prove she is not nervous or something.

-Ever since that day she just sits on her chair and looks at me when she thinks im not looking.

The main question is she is a relationship, what is wrong with her?
