Alright I guess a little background information is at its place.
I guess I am sometimes an AFC but I can be PUA sometimes too. My problem is that apparently I am being attractive to girls when I don't want to (not really a problem on its own) but when I find a girl that I really like, I turn in to that same old nice guy/AFC. This results in a lot of sex with girls I never really thought about having sex with (I still only fuck good looking girls though) and not so much sex with girls I actually try to lay. This happened recently to me, this girl approached me, very flirty etc. and I acted cool about it so we had a little thing going. We then met at a party later that week, and I pretty much just went up to her, pushed her female friend aside and startet making out with her. We then continued to my friends car, had sex, and then split up. I talked to her later again at the party and I ended up spending my weekend with her (We fucked a lot to say the least.) Something changed however, during that weekend I started developing feelings for her, and she for me (I am certain of this because on of my female friends know her pretty well and she said she talked about me all the time). I then proceeded to make all the mistakes. I became that nice guy again (putting her on a pedestal etc.), which resulted in her losing her feelings and me getting kindda sad. We still talk, and even fuck now and then, she occasionally calls me, or I call her whenever we feel like sexing each other, but she have made it very clear that at this point there is no feelings involved on her behalf. The fact that I still lay with her makes me pretty sure that I have not been friendzoned just yet, and that she feels sexual attraction to me. My question is not what I did wrong, because I have already realised this. My question is What do I do now? (aside from moving on) because I don't really want to move on, I like this girl, and I would love being in some kind of relationship, but can I restore her aforementioned feelings or is this a lost cause? if i CAN restore them, then how? I got my own theories, like for instance I should try go get back to what she got attracted to in the first place (The more casual, cool and laid back me) but I also think I should put some distance between me and her, and start talking with other girls, making her jealous and generally make her miss what she had, but how would you guys approach this?
I apologize for the wall of text, and I hope you will take your time reading it!
Peace!
Ps. I don't know if this is the right section, feel free to correct me if I should post it somewhere else!

only one thing you can do. get over her. its a win win situation. her attraction might go up as a result and if it doesn't, well, you're over her...

^ What he said.

Key here is to actually get over her. Don't talk to other girls to try and make her jealous, talk to other girls because you genuinely want to.

But is it actually possible to make her want me again? or does this seem like an unrealistic goal?
As to getting over her, I guess I am already on my way, I got a big party on Friday, and I have already planned to continue my hunt - at this point I just wouldn't mind if I could restore her feelings, if not to date her, then atleast to make me feel confident and feel like I achieved something

Yeah I didnt mean I would do it to make her jealous, I would do it for my own satisfaction, but it would be a plus if it could make her jealous I guess

yes it's possible - but you're asking the wrong question. the question is, who cares if she wants you again? as long as you make this your goal you will not be over her and her attraction will not increase.

I guess you are right.

Well Thank you for your advice

Just move on with life... there's millions of girls within your proximity. Be awesome, keep living.
