That's an interesting experience, still though, the best way forward is to not seek that experience because odds are extremely high you will never find the same conditions nor the same girl with the same reasons to behave in such a manner and regardless it never got serious and you were her willing plaything, you can find better and be better.
Do two things forever starting today, each and every time you interact with ANYTHING even a cat or a dog or something
Walk with confidence, shoulders square upright posture, strong stride etc, and more importantly and more difficult to master:
always make eye contact, and do not break eye contact unless there is valid reason to do so, you can't stare someone down super hard indefinitely without it getting weird but if you take little breaks to look away 90% on 10% off you can maintain excellent engagement and eye contact without being weird about it. Practice it. No one will fault you for making too much eye contact but they will judge you for making too little as being weak, submissive betafish. It will not be easy, it will be scary, it will make you feel nervous but you will not acknowledge any of these feelings for starting today you are beastmode Alpha user, you are fearless and cool, chill and agreeable but with edges that are ready to be drawn any time you are pushed a little too far. You are not afraid of any human being - they too are human, they have fears, emotions, nerves, just like you. You might have been afraid of women because it's "muh different" but that was the old you, the new you is courageous and gives no fucks about 99% of the women he meets, win or lose you keep rolling and don't let any of that shit ever drag you down.
Here's a story of one of my conquests - girl, 6'2" tall as fuuuck sexy because I am tall too so it's like hnnnng you are near my height, I go to her house and I notice she makes literally no eye contact, I am locked on the whites of her eyes and she is looking at the wall and shit while talking to me, she is the defnition of pure betafish in woman form, I proceed to be my now normal Alpha self and escalate, we sit on the couch next to one another, her cat comes up on the other side, I lay both my arms across her legs to pet her cat and just fucking leave them there, once cat leaves I proceed to throw my arm around her and we continue talking, pause in conversation and I go straight in for the kiss, make out on couch start feeling her up advancing my guard bsed on her reactions, this progression happened over the course of like 5 minutes from first meeting her because I observed she was beta as fuck so I went full Alpha mode and we boned, simple, never talked to her again and went home listening to quantum mechanics lectures feeling like a motherfucking boss.
Now, disclaimer: I was not always like this, prior to high school I was the definition of beta, probably worse than you without even knowing you just probability but I decided one day late in I think 8th grade or early 9th grade I don't remember that I was fucking DONE with the beta, I was going to (FOLLOW THE STEPS I GAVE YOU) and fake it till I made it. At first it was extremely akward and I felt false, I felt like I was fucking lying throuh my actions but the positive feedback loop I began to receive as a result of my more alpha posture and eye contact compounded into real confidence for me which resulted in the fake behavior to become my literal baseline. I started doing sports, I was one of three tylers who started a fight club that had 60 members at its peak, I got laid for the first time with a girl who was also a virgin shit was cash, all of this came AS A RESULT OF my changes in myself. I didn't become Alpha by accident, I CHOSE to be Alpha because life is a fucking choice and you can choose to be betafish your whole life if you want but you only live once and fuck it take a risk.
