One thing that I noticed, and perhaps it just wasn't mentioned, is that she never explained why she just left you sitting there. If nothing else "she" at least owes you the explaination for her bad behaviour in that respect.
I rarely meet people from online, and in the few times that I have, I've always been very comfortable with them first. For example, here, I've had dinner with both Matthew, and DJG, but they're both very straightforward personalities here. If someone is cagey in any way, beyond standard safety practices, I pretty much write them off a fakes. My fav experience was a guy that was hounding me (NOT on this site) for months to meet and "hang out". I figured that after such a long exchange, he had to be sincere, so I worked up the nerve to finally meet. He only had a couple available pix, and I swore they looked close, but still I kept thinking they were two different people, but it was tough to tell, and he was such a nice guy. So, guy shows up, and doesn't look like EITHER of the pix. When I brought this up, he became totally indignant and blamed ME!
Him: "You KNOW you wouldn't have met me if I sent my own pictures! You're just mad because you have some fantasy person in your mind of who you were expecting."
Me: "But that's just it. Those pix aren't YOU!"
Him: "Well, that's your opinion"
Me: "You just admitted... GET OUT!!!"
Um... WHAT???
