It's clear she likes him. She didn't exactly tell him but she showed him. Which is what she means by "pantomime". But he was interested in someone else, and she knew but she still continued her affections. "A fugitive too dull too flee" She's going to sit back and watch him love someone else. "I've made my peace i'm dead i'm done, I watched you live to have my fun, I root for you, i love you" And so she tells herself because she loves him she will encourage his love for another which is what she means by "I root for you, I love you".
