TITLE: How do I tell someone I don't like them back.
POST: Name = Person (Age) K = Me (17) A = Girl I like (17) P = Girl that likes me (17)

K and A both like eachother. K and A would both be together but P has liked K for 5 years. K and A are both good friends with P. K isn't supposed to know about this 5 year crush. K and P are going to the movies in 2 days to see Brave. K plans to tell P what is on his mind after the movie. P is also K's ride home. What does K say to P so K and A can both be together?
TL;DR: 
K and A like eachother. K is under dibs by P. K needs to tell P he doesn't like P like that. What does K say to P?
