Is she ignoring my friend request?

I was talking to a girl that was very flirty with me. She gave me her phone number before I had the chance to ask for it. She acts interested, and kisses me on the cheek.

So we hung out one day and she asked me if I had a Facebook. I told her that I did but that I barely used it. She responded with "I don't really use mine either".

So I decided to surprise her with a friend request a few days ago and she still hasn't responded. I know that her Facebook is connected to her blackberry, so she should have gotten it immediately. Also, over the past few days, I've seen her number of friends go down every day, from 737 too 733.

Is she ignoring me?
