Poor Harry. Sounds to me like he didn’t know how miserable he was until Meghan told him. How bad could it be?
Before Harry met Meghan I read that William told Herry that “it’s all right for you” and they were discussing the burden of being royal and having to fulfill all their obligations that are a consequence of their birth. I don’t think Harry was unwilling to start a new life although it would seem normal if he felt torn about it.
We Americans generally don’t know what that’s like to have our destiny in life laid out before we’re born - even on a small scale.
