Is she playing games or just not interested?

I'm extremely confused by her actions. We talked for a bit and hung out but after I asked her out, she rejected it saying, "She doesn't see me that way and had someone else" But was very nice about it and I wished her the best. Although the atmosphere was awkward in our place, she wouldn't ignore me but I'd catch her starring. There was a seating plan and instead of sitting elsewhere in the room she decided she would sit directly opposite me on my table and she'd look noticeably nervous. She'd also want to stand near me instead of anywhere else. Here's the thing though, she'd never want to talk, when I try to talk she'd always turn away and look nervous and she seemed clearly fidgety playing around with her hair and her clothes. She'd also see me in the distance and talk to other dudes when I walk past. I find it irritating to be honest and I'm losing interest fast. Is she running a sleazy scheme or just not interested.
