well, going completely dark has definitely stirred something, but who knows what. She got super angry at first, and now she's doing little "funsie" type things to try and get me talking again. Holding my tickets "hostage until her friend comes back," liking stuff on my FB, sending me pics of her and her bosses at a convention, etc.
Interesting stuff. I'm still thinking and worrying way too much about what she's doing, though.
