I don't know whether I dare post this, but here goes:-

She’s certainly a “tryer”

Take that however you like

It's Meghan with an 'h' and TBF her prince is no more feckless than she is.

Cashing in (or trying to) on her title and royal connections- you forgot to mention those among her achievements.
The self delusion of posturing as a home style guru, cook, a hostess with the mostest and someone who is tone deaf to those around her incapable of reading the room and oblivious to basic good manners too.

That woman has returned to the UK of her own free will.
She seems to me to be the dominant one in their marriage.
Harry is an emotionally damaged young man thanks to the appalling adulterous behaviour of his father and girlfriend which led to the family breakdown.
Miss Markle knows exactly what she's doing. Her status would be zero if they divorced.

Meghan would have done better to have tried royal life for a longer period before rejecting it so rudely.

Camilla was not at all popular when she first appeared on the royal scene but by work, duty (oh how unfashionable) and not taking offence at the many aspersions cast at her she has been generally accepted by the public and is developing respect and popularity in her own right.

Meghan has found out, to her cost, that royal life and celebrity life don’t mix. She always ends up painting herself into a corner.
Maybe a successful celebrity aristocrat like Emma Thynne, the Marchioness of Bath, could give her a few tips!
