Edit: just wanted to say thanks for all the feedback I'll try my best to apply everything you guys told me.

So only around 3 days ago have I really started trying to use TRP and trying to improve my game. I don't really know all the terms and all steps I should take whenever I try to approach a woman so sorry if anything I do might seem cringy. Any help as to where I can improve is wellcome

So I've seen this girl get off the train with me at the same stop for arround 3 weeks now, she's a soldier (not a big deal I live in Israel so it's mandatory for everyone that lives here to join the army at one point) which made me instantly go all blue pills and never approach her and anyways she's always with headphones so I didn't know what to say after I get her to take them off not to mention the crowd of people pushing us all to get out of the station and get to work.

So today as I was waiting for the train back from school I was sitting in the back of the station charging my phone and listening to a few field reports I found on here I noticed her getting in the station and going up the escalators to the same dock I take. I said to myself "fuck it" got off my ass and went up after her. I found her sitting in the back of the dock with her headset listening to music totally zoned out. She couldn't hear me so I had to wave my hand in front of her until she noticed me (I'm so fucking smooth I know) when she took off her headset I didn't know what to say so I just said "hi I've just seen you in the morning here coming off the train and never got the chance to talk to you" to which she replied "oh really? Where're you from?" she lives one station after mine, so we kept chatting and at the start it was totally stiff and most chances red embarrassed since I never approached a woman on the street before. All previous relationships were either met from a friend or online so I had 0 experience.

I was having a lot of back pain since I was working on my posture and standing straight properly. Thinking of the pain reminded me of everything I read and I started applying it. I teased her a lot, lowered her self value while increasing mine, she quickly changed her approach constantly laughing, smiling and fully engaged in the conversation, her body language showed a lot of interest with her fully facing me and her eyes couldn't get off me, I tried my best to keep by body language casual, half facing her trying to make it look like I couldn't care less about this talk (even though on the inside I was fucking so giddly like a little kid. I can't believe I'm not a virgin either). I had arround 80% control on the conversation only at the start where I didn't know what I was doing, there was one awkward silence for a second but I brushed it off poking fun at her for going "ummm" where she laughed and blushed.

Now here is where some problems started happening because she gave me a lot of mixed signals. She was totally comftirble with me touching her, high fives, holding her hand, touching her cheeks and hugging her, but she said she has a bf multiple times. At first I thought it was a shit test and pretended like I didn't even care ignoring it. But then she kept talking about him and makes it seem like it's a real one. Yet at the same time she can't stop smiling and talking to me.

She gave me her number and we kept talking after I got off the train. And I have been trying to get her to meet me up for ice cream but she said she's afrraid her bf will be jealous.

I'm going to see her tomorrow when I get off the train and I honestly don't know what to do in this situation so the more help the better.
