With regard to the OP, I am becoming increasingly sympathetic to Ms Markle. She has prospered in life, quite unlike her ne'er-do-well siblings. Their jealousy and contempt is evident for all to see and they have demonstrated that they will stop at nothing to cause her the utmost embarrassment and distress in front of a world-wide viewing audience. Any hopes of a reconciliation are, in all likelihood, now lost forever, but they probably knew that from the very outset. Even her father has turned out to be a grasping opportunist.
However, the bride to be can act (being the operative word) every inch the lady, the dutiful partner, the humanitarian but one must wonder how well bred, beneath the polished surface, a lady from a family such as hers can possibly be.
