As with the prodigal son in the Bible, all you can do is let them go their own way (with no enabling) and let the chips fall where they may. All the Windsors but Halfwit seem to know that a divorce will happen because of MeGain’s life pattern, so they will bide their time. The flameout of these two in Hollyweird will be interesting to watch. Who will MeGain’s next mark be? Will Halfwit develop any character, maturity, self-awareness or humility through it all?
The prodigal son was a character in a parable, a fictional story. This Markle malarkey is fact; all you can do in response to it is not governed by a made-up response to the waywardness of a fictional character, is it?
They will follow the pattern set by the Duke of Windsor and his horrible wife.
