Girls, Why am I suddenly nervous around a girl who i've spoken too before?

Initially I was comfortable her, she and I have hit it off really well and we could comfortably talk with each other given we were strangers. She accepted my friend request on facebook. But now I just feel nervous towards her, she is still treating me nicely and all that. But I just feel nervous around her like I can barely talk.
