This is a common occurrence, a regression into AFC mode after the initial attraction phase is over. It happens because you haven't internalized the stuff you've learned yet. Acting confident and using PUA techniques to arouse attraction is one thing, having a PUA mentality ingrained into your game is something completely different
It seems to me like you somewhat have the first part down, you know how to build attraction and sexual tension. Work on inner game now.
As for this specific situation, I don't think you should defriend her on face book. You have to withdraw attention and TAKE HER OFF THE PEDESTAL she is currently on. If you defriend her and go out of your way to make her jealous, you're only reinforcing the idea that she's on a pedestal. You're giving her too much importance. When guys do things like burn their ex-girlfriend's photos or go out of their way to shun a girl who has rejected them, their actions end up having an even GREATER symbolic importance.
My advice to you is, cut your losses and move on. This accomplishes two things and up creating a win-win situation for you...
(a) She ends up missing you and seeing that you are with another girl. Her interest level increases because you are WANTED in the social market. You get another shot at her, this time don't be a wuss bag.
(b) She doesn't contact you again, BUT, you've moved on so it doesn't matter anyways. The best way to get over someone old is to get under someone new.
On another note, admire beauty, but never worship it. Just because she is the cutest girl you've ever met doesn't mean anything. Beautiful people are simply lucky. Beautiful women have been treated with too much attention since they were born so they're on the apex of a pyramid by the time they can walk. If you treat them like their on a pedestal, you fall into the same category as the thousands of chumps she has LJBF'd throughout her life.

I get good results with women and one of my top rules is that if I find myself getting to mushy towards a girl I will either be a complete dick to her the next time I see her and see how she responds or I will erase her number
that sounds intense, but I have a ridiculous amount of respect for you dude, that's dedication right there. Self mastery > Girl Mastery
