He should have stuck with the Saffer/Zimbo blonde bird, Chelsy. He would have got plenty of sex, plenty of blow jobs and got to go to Southern Africa on a regular basis shooting Lions and massacring the local wildlife in the best traditions of the Royal family.You are assuming that they will still be together, Arrse wisdom has them down for five years, and Arrse is never wrong.
Once Her Meganness finds that she is not the major celebrity that she supposes being Duchess of Suffolk brings in her home country then how long do you think she will take to extend her headline grabbing by ditching the deluded Ginger one.
She will then lovingly harp on about all the misfortunes inflicted on the unsuspecting dusky skinned American lass by the Royal Family, the lack of understanding by the British Public, the horrid British Press, and how life with Ginger was not all it was cracked up to be and descended into a cold hell with him.
Finally she will hold young Archie up as an innocent victim of all these machinations and claim loads of moolah as his birthright.
She thought that becoming a Princess would make her automatically famous and beloved like the Sainted Diana with people fawning all over her. When that didn't happen she went into default setting imagining that her Royal status could be parlayed into regular Hollywood style fame, that somehow getting married to a Royal made her a big star.
Reality will hit, though I doubt she is capable of self-criticism and it will always be someone else's fault.
Interestingly the two American 'ladies' who married into the Royals had a romantic, American idea of what it would bring them, and both ended up disappointed in a self-semi-exile. She's kept up the 100% record at least.
