LOL I feel ya man. I was in the BFF zone for a while, then tried to game a girl without taking a break... Lets just say the last few months were interesting (VERY emotional and confusing as hell, but interesting).
The thing about this kind of relationship is that the girl "loves" you, but she doesn't "lust" you. They care enough about you to make you happy, but it's not the same as a lover

. I came to the conclusion that this is the reason pickup works: Lust > Love.
Basically, I'd say do what I'm doing: take a breather. Even though I COMPLETELY AFC'd EVERYTHING, I'm giving myself time to change my mindset, skillset, and confidence level and not talk to her (I even told her I need a break after I AFC'd and looked 100% needy/desperate [even TELLING her that is AFC obviously]). After all those things are accomplished THEN decide if you want to get with her after you've made progress with pickup and shopped around a bit.
I believe our situation is shared because it appears that you care about her and she cares about you (basically a relationship without lust). We just have to pull through it and cut our final tie from being PUAs. It's a hard way, but I'm about a week into my decison and I'm starting to feel a lot better about it.
Hopefully this helped somewhat
