You know how some people see what their ex has become/done after they split and they think "ahhh thank goodness I left and I'm not the wife dealing with this behaviour, embarrassment etc"... Well I bet Chelsea and Cressida are bloody relieved. I think Meghan is 50% the cause of his antics, but I still think had H married Chelsy or Cressida his jealousy of William and of being the spare plus his personality and drug use would probably still have led to some public outbursts, and I still think a book would have happened. The difference is Meghan got him to do it with her permission and partially her masterminding, whereas I'm sure C or C would have been mortified wives and not condone his behaviour. I think we'd have been like H, you are embarrassing your doting wife! Shut up!
I think he'd have been a disaster for any wife. Any wife of his in the future would have to be stupid to get with him unless he does a 180 degrees turn, sobers up, repents, apologises and calms down, which I doubt.
