On meeting others

So, I was talking with another CD about possibly meeting with her this weekend.  If we were to meet, I'd have to drive a ways to meet her.  We last talked Monday, where things were going smoothly... and then she practically dropped off the face of the planet for the last three days, despite IM messages and emails to her.  I'm kind of upset - I mean, if something comes up, and you can't make it, fine, just drop me a line.  But to be totally incommunicado?  Very frustrating.  I just hope she pops up this afternoon online so we can figure out if we're still on for tonight or what...
