I don't think this is Meghan's 'fault'. But what I do think is that she is using it to make herself come out looking better - she stopped talking to her dad around the wedding in 2018. She wrote the famous 'Dear Daddy' letter to him in late 2018.
This letter from his ex-wife was shown to her in 2019.
Meghan is now trying to say that she cut contact in order to protect her children from his alleged paedophilia, knowing that we'll all agree and she will look like the victim, yet again, of a critical press. And she will also be hoping that this will mask and maybe exonerate her of the forgetful collaboration with Finding Freedom, the veiled accusations of racism in the Oprah interview, the subtle trashing of the Princess of Wales in the same interview, the 'the Queen doesn't have jurisdiction over the word Royal outside the UK' comment on their website regarding the Sussex Royal branding etc etc.
She and Harry are professional victims.
