She's doesn't love Jamaica, she loves being a white woman in Jamaica and the attention she gets from Black men there.
here in America she's just a basic white girl because there are many other white women for Black men to choose from, out there, she doesn't have much competition from other white women especially given the fact that she's absorbed much of the culture and can perform patios to get extra brownie points from the locals.
She's a white girl who works tirelessly to put herself in competition with Black women who don't have to try as hard as she does to gain attention from Black men, that's why she had to go over the top with antics, the head-top, always professing her love for Black men, separating herself from other white women because "I'm different", etc.
