This kind of stuff sucks, and messes with your head, but it's just how (immature, indecisive, fleeting) girls are. That's why recognizing this crap is so important, so you don't get sucked in by AW's, or girls who toy with you and send mixed signals. This is also why you don't give away your power, make it all about them, hang on to a linger of hope, etc.
But I think you moved too fast - especially with regards to sexual escalation. Any kind of moving too fast, pushing too hard, or showing too much interest too soon, and not allowing them to chase, results in low interest and rejection - as you witnessed here. ****, you even made your intentions well-known, were aggressive, pushed for the physical right away - and STILL got FZ'd. Completely going against the claims made... everywhere. That's why you always gotta play the game - even as you're showing bits of interest and escalating.
It's not just what you do (ie, being sexual and assertive), but how you do it (ie, presenting a challenge, having value, letting them chase and win you over). It's all part of the same game.
I learned this one after being the passive nice guy who never escalated or asserted himself... I switched extremes, and became the super aggressive sex hound. Yea, didn't work. Still got rejected and FZ'd for trying too hard and coming on too strong... Just in a different way.
It wasn't what I was doing that resulted in failure, but how I was doing it. I had a lot of game - without actually having any game. I was just very shy, insecure, distant, aloof, and passive (with attractive women)... But very social, attractive, out-going, etc (with everyone else). So, girls would approach, talk, flirt, escalate, and I'd just sit there like an oblivious dumbass. Never struck when the iron was hot, acted way too friendly, and they eventually found out my true colors (needy, insecure nice guy), which went against why they were initially attracted (in-demand, indifferent, high status guy with options and game). All based on perception vs reality; interest vs non. Sad... Shallow... But that's how it is.
Just gotta put the pieces together, and find the right balance.
