How To Get This Girl?

I'm Currently In The Kinda Friend Zone. Me And Her Have Been Best Friends For Two Years . We've Gotten Close This Past Week. I Spent The Night With Her And Her Best Friend, At Her Best Friends House. My Crushes Name Is Kelley And The Friends Name Is Brianna . We Were All Laying In The Bed , I Was Between The Two Girls, Kelley Passed Out While Me And Brianna Were Talking. Kelley Randomly Started Spooning With Me, Like Her Leg Was Over Me And Her Face Was Faced In My Neck . Kelley Doesent Normally Sleep Like This, Brianna Told Me That This Is The Only Time. Well I Couldn't Sleep In The Bed With Them, So I Went To Lay In The Floor Prying Kelley Off Of Me. Well Kelley Was Trying To Cuddle With Brianna Afterwords Saying Things In Her Sleep Like Saying She Loves Me. Brianna Told Me Shortly After, Then Kelley Turned And Started Rolling Off The Bed, After I Catch Her Atleast Four Times, We Wake Up Kelley And Asking Her Why She Was Slleeping Like This. She Told Us She Took A Pill That She Took For Head Aches , I Told My Mother After The Night. My Mother Said That She Lied About The Pill Thing .. Well She Still Considers Me A Friend And Stuff .. I'm Spending A Night Again Soon .. What Could I Say Or Do That Could Change How She Feels About Me ?
