She already lives in a first world country of England, she is already wealthy as she claims, so what is it she is after then? Fame? Reality show career? Something isn’t adding up.

I think she grew up with some level of “new” money and her living in different countries, combined with new money help or gifts when she was younger, gives him this chip on his shoulder that he’s also using against her. I think the producers are pushing this angle because otherwise, they have nothing to argue about other than he’s an asshole.
