People are stupid, they aren't that stupid. Your silence and absence speaks volumes. What they say publically to her and what they think to themselves are 2 different things.
But more than that, you owe her zero. Zeee fucuking OOOO. There are tons of people that know about her and her show, guarantee it. Been there.
It's so trite, but the real best revenge IS living well. These fuckers, your mother, my mother (now dead), my family and haters, they so want to see me fail. They want to see my heartbroken. They want to see my husband leave me. Never going to happen. I'm going to live over here and all you clowns can watch and fantasize and hope, but we're good, go clean your own shit up.
You're awesome and brilliant and strong, THAT'S your revenge. You're going to be a household name and then they're going to scramble with, "I knew her when..." FUCK THEM ALL!
