What could a this mean? If it means anything...?

[m c]

I know this sounds dumb but.... I'm a girl and I'm bi and I like this other girl she hugs me around the neck at times and I end up hugging her around the waist and we are up close to eachother, there is no distance between our bodies. I was wondering if anyone had any opinions on what this hug could mean, if it means something? She doesn't know I'm bi yet and she has hugged me like this a few times and Idk if she is into girls at all. her facebook says she is into men but I used to lie on my facebook page before taking that part off of my page.
