Your view on this matter is kinda wrong. PUAs don't claim to know the only way to getting girls. Those who do are either stupid or lying. Rather, their focus is to give themselves the best shot with as many high quality girls as possible and to prevent heartbreak. PUAs who come up with classic stuff like 'move on to another girl', 'once you blew it, it's gone for good' and such beliefs which are in essence self-limiting beliefs, aren't actually that good and pretty much lack experience themselves.
Let me give you Chase as an example. If you've been following girlschase for a while, and have read many articles, you will notice that as time progresses his views change, which is natural for any human being. Here's an example:
https://www.girlschase.com/content/attr ... ation-date This is one of his most popular articles and it dates back to 2011. You can definitely tell that it has a quite extreme and short-sighted view on attraction and its supposed expiration. I recommend you read it, though. Fast forward to 2017 he came up with this article on pretty much the same topic:
https://www.girlschase.com/content/attr ... or-it-isnt
This article is almost the complete opposite of the former. While in the first one he says that once a girl loses attraction, she's gone for good, in the latter he says that attraction can definitely be rekindled IF it was there in the first place. Why is that? Because as time progressed he got better, he gained more experience and broadened his view on this matter as well as others. There are many such examples on his site, this is the one that came to mind right now. I personally found out the latter to be much more accurate, from my personal experience.
Also, ever since I've been applying PUA stuff, while I've gotten so much better with girls, I've noticed that certain PUA techniques don't seem to work on most girls. Don't forget that PUAs are aware of the fact that you will get together with a small percentage of the girls that you approach. Why? Because many techniques are designed to work on basic female psychology and ignore stuff like the girl's thinking (women do rationalize, they just do it after they respond emotionally to something, unlike men), her personality etc.
For instance, I've noticed that throwing the ball in a girl's court doesn't usually work. I've actually never made it work, yet it's claimed by PUAs that it's the best shot you have if a girl flakes for instance. I found this to be absolute bullshit and I actually found the reason why: if you want a woman to chase you, she must never realize that she's actually doing that, much like you don't realize that you've been chasing the girl you've posted about. By throwing the ball in her court she instantly rationalizes 'oh, he's trying to get me to chase. I'm not gonna do that'. So you might still have a shot with that girl and she might actually want to see you if you persisted, but because you're not persisting she thinks that you're playing her or whatever so she goes into auto-rejection and that's when you lose her. That's when a PUA would say 'she didn't respond to you throwing the ball in her court because she didn't actually like you'. That's total bullshit. However, as I said in an earlier reply, your girl seems to actually responding to this technique so you can do it in this particular case.
Here's a recent post that I made about a girl I also want to get back:
viewtopic.php?f=3&t=19900
In my latest reply to fog I mentioned how I accidentally ignored a text I got from her and we had a date set that day. She got mad and cancelled the date. I then explained myself and she stopped being upset and made a counter-offer. So what I did was to follow PUA advice and to not accept a counter-offer I didn't like. So I declined her counter-offer, thinking that she's jerking me around (that was not the case) and told her that she's gonna have to do better than that and that she'll have to ask me out the next time. What happened? She obviously never asked me out because she realized I'm trying to get her chasing (even though she was chasing up to that point, she just didn't realize it, but she did now), she went into auto-rejection, I did some more bullshit which got her thinking that I was playing her (which i kinda was) and that I didn't care about her, we've been fighting and I've been trying to get my attainability back up ever since, and have only had a bit of success lately.
So in the end, leave your girl for now, focus on fixing your mindset and curing your neediness. And you absolutely MUST follow Dan Bacon's work as well as Todd Valentine. I recommend watching Dan Bacon's video about getting out of friend-zone and Todd Valentine's video, featuring RSD Max on how to persist without being needy. If you want to perform a comeback with your girl, those two videos will be the basis of your comeback. Still, give her a month of no contact. If she follows you on instagram or whatever social media platform, post ever once in a while pics, videos, stories whatever of you having fun, try getting some girls involved if you can. It will ease your comeback. In a month time I suggest you come back here and read your op on this thread again. If your reaction will be something like 'gosh how needy I was', there's a good chance that you've fixed your mindset. Hit her up and be ready to persist.
Also to answer your other question, I'm actually very confident that i can turn any female friend of mine into a potential lover. I actually almost did it with a girl who I never thought would ever have any interest in me. Over the course of us hanging out two times i got her from never wanting to flirt with me, to always flirting with me, touching me, wanting to meet my mom, being insanely approval seeking, holding hands and her inviting me over at her place. It's insane what you can do with good kino and a good flirt and that's what Dan Bacon teaches but this requires a lot of confidence in yourself and a carefree mindset. And yet again, good kino and good flirting abilities. So to answer your question, yeah, you can hang out as friends and turn it around but judging by the way you're presenting yourself over text, I'm not sure you'd be able to do it at this particular point in time. I believe that courting her is the better option for you. Yet again, follow Dan Bacon and if you feel like you can do his stuff (it's not advanced stuff at all, it's fairly simple but, yet again, it's all about mindset) then yes, you can accept being friends with her. However, even as friends you will still be sexual, you will flirt with her, use kino, be a challenge etc. Just start watching his stuff and see where it takes you.
Good luck, bro and if you have any success let us know.
