the way i see it you can handle it like this..
build her investment in you by getting her really close and attached to you on that friendship level then detach yourself from her suddenly without warning so it switches the chase dynamic & then in like a month get in touch with her again and reframe (research it if your not sure what that means, its important) & use more attraction game and less comfort game... and use the friend thing to disqualify yourself & build her attraction even more...
like.. You get her to give you an IOI
for example:
Her: I missed you..
You: liar You just want me for my body.. your not gonna get me in bed that easy
Here shes either gonna laugh or qualify herself depending on the level of attraction you have going on. You want her to qualify herself so try and build the attraction and make sure theres a lil sexual tension before you do this.
Her: (Random Qualifier) "I could have you if I wanted you" "oh you wish" "You want me in your bed"
You: Are you hitting on me? (with a Oh isint this Ironic delivery but a playful frame)
role reversal
Think of it like scary movie 2.. when she said I think we should just be friends.. and he spends the whole movie treating her like she was one of the guys lmao.. like that.. just verbally dont beat her up like in the movie obviously lol..
if you act sensitive with her ur getting sucked into her frame.. Be a Dick.. Suck her into Your reality... & make her believe it.
