Well travelling from all over to marry their Princes doesn’t appear to have done Mary, Maxima, Charlene et al any harm. I mean they haven’t keeled over as yet
Mary all the way from Australia to become a Danish Princess, imagine that? Maxima from Argentina to the Netherlands. These were previously high flying career women. South African sportswoman Charlene left it all behind for her Albert. There’s also the French Marie. Plus a few other women from other countries marrying into the British Royal Family.
Meghan will do just fine, she loves charity work and had her acting to put a roof over head, a job she obviously enjoyed. But whereas before, her charitable endeavours were time-limited, she will now have plenty of time to devote herself fully to a career of charity work on a much bigger platform. She also wants to start a family and at her age a change of direction regarding her acting career was likely needed anyway.
