Right sorry for the delay in getting back to report, I've been away as you can see!
Basically I continued to keep in contact with her as much as possible without being needy: texting like once or twice a week, saw her at school and deliberately went over talked to her, strong eye contact, flirtacious teasing, talked about past positive experiences we had shared*
She seemed to respond well to this with the usual IOIs etc.
However what really fcuked me over was what I call a "dry period": her going away for like a week, then when she got back I was away for a couple of weeks, then we had an exam period of a few weeks where everyone is mostly 'head down and work, socialise post exams'. This period of 5 weeks or so acted as a proverbial cockblock.
During this time I found it virtually impossible to keep up contact and therefore attraction. There was a party where she was quite positive, stating a song always reminded her of me, taking 10% of her night's photos with me...
...but this was an anomalous night out of the "dry period".
When I got back to college I barely saw her, and if I did, not to speak to; things were not like they were before. The attraction had kinda dried up, which was annoying as I had been in what I perceived to be a promising position. Instead I had gone from regular contact to virtually none (but I thought oh well move as it's out of your control)
During this "dry period" I sent her a text on SexAddict's advice describing a 'dream' I had had with the two of us, so seemingly real that I HAD to tell her: vividly describing how the song reminding her of me came on, then she pressed her body against mine, dancing seductively then kissed me passionately.
Her response I would say was pretty warm, not totally wet by it but it certainly piqued her interest.
THEN, just recently she popped up out of the blue and was like "hey where've you been, I haven't seen you in ages! How are you?" Interest is still there but from what I gather from her friends she has an unofficial bf now which is a bummer.
All it means is just that it's time for me to move on for now. Game her later as she's clearly still targetable.
LESSONS/LEARN FROM MY EXPERIENCES:
May seem obvious but ensure that you maintain contact with her otherwise the attraction just dies.
Reminding her of positive times spent together will get her giving you some emotional attachment which is v.v. good for you and thinking about you.
(*More on this - I wanna do another post as I feel it deserves its own)
It helps to just surround youself with girls when targeting the girl for
a) builiding comfort with them
b) confidence around them
c) other girls will see and see you in a more sexual way/attractive - I found I attracted 4 other girls just by doing this whilst going for my HB9
d) your value goes up in the target's eyes
Note: don't be overly flirtacious with the non-target girls otherwise your HB may get jealous (which will likely backfire for you although not always)
If you wanna try and gauge her interest, use SexAddict's tip of a 'dream text' and be bold with it. Make sure it's descriptive and vivid so she can visualise and fantasise. It doesnt really go wrong. If shes not into you then or gets slightly distrubed you just say "hey it was a subconscient dream, not real!"
Anyway that's it, unfortunately not a succesful close but I see it as a learning curve and all good experience. Fate determines what happens for good reason. And who know's what the future holds.
Hope that helps someone - give me a shout/reputation if it does please!
