There is a reason people are calling him "Handbag Harry".
He has become an accessory at this point.
Ms Markle is a hot mess and probably the best thing that could happen going forward, is she finds a Russian Oligarch to take flight with and let Harry crawl back to his family where the Monarchy's PR machine can begin a campaign to revive his image.
I predict in 10 years Harry will be living in Africa with a suitable European wife and carving out a wonderful life there in Africa, a place he appears very drawn to.
