Sudden change after setting second date?

I asked this woman for a second date, she said yes and invited me to her place.

Ever since we setup that second date, she has basically only replied when I asked her adres (she did send it). I told her, I was looking forward to seeing her and i got no reply again.

I don't really know how to respond to any of this. She isn't saying no to anything but the extreme lack of communication is making it weird.
