'He actually adds that he wants a family, not an institution.'
You know what? I think that would have been perfectly possible. Meghan could have continued her acting career, Harry could have continued in the army (there are loads of jobs he could have done without being on the front line) or been a serious advocate for veterans.
They could have joined in for stuff like the jubilee, exactly the same as Zara Tindall does, gone to Balmoral and Sandringham to spend time with his family.
Instead they've blown their chances sky high by their monetising of the relationship with the RF, the insinuations, the untruths, the ridiculously dramatic interviews/docudramas.
