I was in a similar situation and I ended up getting a girl who friend zoned me to fucking ask ME out
if you really want this girl you are gonna have to do quite a lot of work to get her.
I know master PUAs talk about how freezing out girls can be effective and don't get me wrong it can but only if you are a master at generating attraction and blasting through awkwardness if this is not you then don't do this.
For me I used option 2 you should act like you wanna be friends with her and then game girls successfully (key word there is successfully if you fail in front of her you lower your value) in front of her, bring HB's to any social event both of you will be attending and make sure to introduce them to her but generally pay more attention to the HB you brought along than her. The hotter the HB is the more effective this technique is in fact if the HB is hotter than her it works perfectly every time.
What you are doing here is demonstrating 2 things: one, you are showing that you can get with any girl you want and are a man in demand and two, you are giving off the impression that you don't like her.
Here's the catch though if you pay no attention to her and constantly demonstrate that you are not interested in her she will just give up on you. This needs to be timed well but when it looks like she is on the verge of giving up or leaving, you need to drop an IOI and it has to be obvious enough to grab her attention, no subtle body language bullshit. Now this will confuse her because you are giving mixed signals, do not worry this is good.
If she asks you to clarify what you meant or asks you explain if you have feelings for her make your response mysterious and vague not really giving her an answer. And then continue in giving 80% of your attention to the HB and 20% to her for the rest of the social event. Now once you have gotten your point across that you are pre-selected just start gaming her as you would a normal girl and remember to escalate as soon as it is socially acceptable to do so or she may friend zone you again.
Also you need to maintain the image of pre-selection so every now and again bring along a HB friend or when she is losing interest game a girl successfully in front of her. One thing that worked well for me was if the HB friends I brought along would flirt with me at some point in front of her. Honestly man jealousy is a beautiful thing and people naturally want what they can't have so you need to make her feel as if at any moment you could leave or lose interest in her up until you can start gaming her properly.
Hope this has been helpful bro! Fill me in on whether or not it works or if you need any help with it.
