I have been in this exact position!! Except I was the girl being gamed by my (now boyfriend).
I met BF because I was dating one of his work colleagues who was so AFC it's not even funny. He would do EVERYTHING I asked but I think he only wanted me as a trophy girlfriend because everytime I would try and talk to him about serious things that were on my mind or something, he would be like "yeah babe" and he never really was on my level intellectually. He sort of forced me to dumb myself down for him. I also always got hit on by his other work colleagues and friends and they would do anything I so much as hinted at - it was fun for a bit

but then I just got bored of walking all over these guys
ANYWAY, obviously (now) BF knew that we were dating and he tells me now that he wanted me from our first meeting but he bided his time. BF ran "stealth game" on me for a long time. He would neg me, escalate kino, keep an air of mystery around himself while constantly DHVing himself and subtly DLVing the guy I was dating and the other guys who followed me around. He used the push pull theory strongly and it is what made me se attracted to him. He would also LISTEN to me when I spoke to him about serious issues and he was definitely intellectually on my level (if not a little more so

) I loved that I could actually talk to a guy about serious issues which were important to me and that he actually seemed to care about them too. We had some great debates about issues and he would respect my point of view. It felt like I wasn't just a "pretty face" to him which is how other guys tended to view me.
We became very close friends and I left the guy I was dating and was single again. One night, we went out for dinner togehter (as friends). I had an awesome time - BF made me laugh and intrigued me with his PUA games (the CUBE and other personality tests - five lies games, etc) and I constantly wanted to know more about him. He kept holding back, but as soon as he felt he was losing me a bit, he pulled me right back in by revealing a little something about himself.
We sort of began seeing each other and I had developed feelings for him and I knew they were reciprocated. The most frustrating thing to me (but it also kept me coming back for more!) was that he wouldn't kiss me. Everytime we were in the moment or something, he would pull away. It drove me CRAZY! When he FINALLY kissed me (on our 5th "date"), it was unbelievable.
He then showed LMR before we were about to have sex, pushing me away again! Of course, this drove me crazy! But the night we did finally have sex was the most amazing night of my life and we have been together ever since (more than 2 years).
So there is a little bit of advice for you if you are planning on having a relationship with this girl and if she is anything like me then this is how you can get her.
Good luck! Hope this helps.
