The anonymous friends bashed Thomas and claimed the Duchess was so upset by his public attacks on her that she penned a letter begging him to stop.
The letter also detailed how Meghan and Harry tried to reach out to her father during the week of her wedding, with Meghan claiming that she only learnt of Thomas' heart-attack through the press.
"Daddy, it is with a heavy heart that I write this, not understanding why you have chosen to take this path, turning a blind eye to the pain you are causing", Meghan, 37, wrote in August 2018.
The letter continued: "Your actions have broken my heart into a million pieces - not simply because you have manufactured such unnecessary and unwarranted pain, but by making the choice to not tell the truth as you are puppeteered in this. I came by there one day, and she had ordered an incredible ice-cream and sorbet stand for the office", the insider revealed. I called and texted ...
"You watched me silently suffer at the hands of your vicious lies".

He said on the television show Good Morning America: "While the objective of Meghan's letter was very much to fix the relationship with her father, she knew in her heart of hearts that this was going to be released to the papers".
'There was no loving message in there, nothing asking about my health, nothing from her saying, "Let's get together and heal our differences", Mr Markle said about the contents of the letter. However, he denied Meghan Markle's claims that he hadn't tried to reach her and showed the publication texts to prove that he has tried to contact Meghan Markle and his son-in-law.
Until evidence proves us wrong, we'd like to believe the latter, that Meghan is in fact, not hard to work with and that her work ethic is just one that many are still acclimatising to or something along those lines.
He also claimed that he chose to share the letter now, after being attacked by Meghan's friends, to prove the tone of the letter was not as it was made to seem in the People interview.
However, Kensington Palace has not addressed the letter, and a royal insider says that the duchess has no plans to comment, fearing it could escalate an already hard situation.
