She's saying "I will change him" but mathematically speaking, that's impossible! The guy is represented by an eigenvector with eigenvalue 1, meaning no matter what transformation she applies, he'll stay exactly the same - just possibly scaled. Linear algebra doesn't lie, girl! That 2×2 matrix she's bringing to the relationship can rotate, reflect, or shear all day long, but his fundamental character (direction) remains unchanged. It's not just relationship advice - it's a mathematical certainty!
