I hope this is not offensive, and I am going to break down why Im asking this in a minute, but - are you autistic or do you suffer from aspergers?
Now the breakdown of why I ask that...
1. Very articulate of your feats (make a lot of money at 22)...the meeting of this girl at the party...the play by play of the hookup.
2. Mentioned you fall in love almost immediately (which typically is someone that has social or emotional issues and cannot 'read' social queues/peoples intentions). People that desperately long for or search for 'love' and attention tend to JUMP into things without thought or considering the consequences. They jusy want to feel GOOD and have someone give a damn about them...
3. The fact that you label girls as cruel, users, and play men like toys (refer to #2 -demonizing ALL females as users because you misread the signs from 1 or 2 of them that you have come in contact with intimately). I believe you said you had never had a gf before?
4. Obsess on a topic/person (you said you re-analyzed the situation over and over, you questioned how she can fall in love with you and then cut you off). I mean, you made an entire post here on misunderstanding a one night stand! Hookups are just that - you drink, you say dumb stuff, and you have sex. If the hookup is good, you stay in contact. If the hookup is not to your liking, you typically 'ghost' that person.
Im sorry you got your feelings hurt. Dating these days can be a maze to everyone...and it is frustrating. People day things to get what they want, mean things, and lies. It comes down ti following your gutt. But your description of the interactions you've had with females just kinda screams social issues. I may be wrong, and if so I apologize. I dated a man who had aspergers (didnt know till the end of our relationship) and his ideas of dating are like yours: he felt ALL women were liars and cheaters. He was uncomfortable in social settings and had a hard time reading people - their faces, their intentions, their actions, their words (jokes and one liners always went over his head). He fell in love almost immediately (told me he loved me in less than 2 wks of us dating/becoming intimate). When we broke up after only 6 mos, he obsessed over me and our breakup, despite me asking him NOT to contact me - he kept trying to (I had to block him). And I can bet to this day, he still blamed ME and all other females for hurting him, using him, being cheaters and liers. 😧
