Hi Jemian....
I agree with your analysis. Ms. Markle realized that unless you’re the centre of a royal wedding, or having a royal baby, it’s pretty mundane when compared to the constant attention of a Kardashian-like celebrity. Ms. Markle would be a distant thought of the American press, once all the hoopla stopped.
She wants attention, fame, and, most of all, much more money and the freedom to do what she wants. Rules of the royal family be darned.
