The situation is this: I met this girl in my country a few days before going to university in England for 2 months. She's 17 and I'm 20. I've never had a gf before (I'm learning the game), and as far as I know she didn't have a bf either. She's a good Catholic girl, HB7, sociable and sometimes trying to be alpha. She's also a leader of a Christian rock band consisting of girls only.
Managed to make her attracted to me, and maintained the attraction online. She was chasing me pretty much all the time: initiating contact, proposing talking on SPAM, being jealous about other girls that I was telling her about, being excited about me coming back, imaging that we meet, etc.
Things changed when I came back. I messed up the 1st date. It was just boring. But then I fixed it - I was invited for a rehearsal of her band and I was fun, dominant and managed to make her a bit jealous. Then I proposed the 2nd date. It was like:
(...)
Her: Errr... I don't know...
Me: We're meeting up and there's no discussion!

Her: Hahaha...
And eventually she ended up coming terribly late, because she wasn't quite sure if we're meeting up. I seriously told her off on the phone. She went out even though her mommy didn't let her go, was apologising me and giving me lots of iois and eventually we ended up cuddling, then I walked her home holding her hand and we kissed goodbye.
Here is when I started making mistakes:
After a few days we met again at my home, and again we were cuddling and kissing. But this time I came off as needy. She was shit testing me by standing up to check the time in her phone and then she was sitting like a meter away from me and then I was like: "don't run away from me..." - embarrassing, I know...
Also I seemed to had forgotten how to flirt online (but I've already fixed that

) and she wasn't initiating contact that often. She started answering me like after 3 mins with one word etc, rarely texting me. She's not that much into me any more.
Yesterday we met again at my home and I decided to try out another tactics. She sat down on the chair and me on the sofa. The plan was not to do almost any kino, unless she does something I could reward her with it. Now I'm thinking that this might have been even worse, because although I was confident she might have thought that I wasn't persisent enough, or didn't have enough courage to say "come here". What do you think? (But we kissed and hugged goodbye)
I said I wanna see her on Sunday, she said we'll see - it's like that all the time.
I'll still be in my country for 1 month and I really want to make her my gf officially. Even if she loses her interest when I go away, that would massively improve my inner game.
But now I'm just chasing her all the time. She feels too sure, and also probably repelled a bit by my clinginess. What should I do make her chase me? Freezeout would take time... Should I try to make her jealous? How should I send her mixed signals? It's clear to her that I'm attracted to her, and that I see her as a gf, so meeting other girls wouldn't work either, would it?
Also what is a good way of handling these shit tests? What kino to do in order to build the attraction, rather than be clingy? (I don't wanna bang her, I just wanna make her attracted to me again).
