Crush acting cold all of a sudden?

So my crush has gone from hot to straight up cold. She has been showing strong signs of interest up until this point...and now for the past few days she's been acting like I don't exist (I can feel/sense that she is ignoring me..and the way she positions her body around me kind of shows it too - her back is always towards me whereas before she was always facing me).

We have talked numerous times and I'm 110% sure that it wasn't anything I said that would make her ignore me. I'm not really sure what to do at this point...right now I'm pretty much acting like I don't care which is probably a bad thing.

Could this be a sign that she's not interested anymore?
