You were falling for her and she ripped the rug right out from underneath you. She talked a big game. You had a good feeling about her. Then she stood you up. She didn't call. Didn't text. Didn't email.
She's a bitch.
Do not blame yourself, even if there were a couple of things you would have done differently, they certainly weren't deal breakers.
You do not have my permission to waste another minute thinking about her. You get your single ass back out there and find the right one.
