We all make mistakes in life , either through lust/love,fear,ignorance,coercion or mental health issues.
I think they Harry knows he has messed up, getting out of this situation if he wants to is going to be difficult for him and the Royal family.
I quite like the chap, He's served on the front line, started the Invictus games and up until marriage was an independent good egg.
The best for him, I think separation would be the best option,just leave the baggage behind, he can come and doss down here if needs be.
His appearance and demeanour point to mental health issues , he needs to get out from under the thumb ,now for his own sake.
