I dunno. I had one guy cancel an hour before the date, but at least he cancelled. I've had "poofers galore" these last few weeks.
I've learned to never get my hopes up until I meet someone. The "leading up to the date" is very much in the "might be a poofer" grey area.
I have, dangerously or not, learned to be very detached from the entire OLD arena. Why I'm now taking a break...
