We don't know how TM went from best possible and generous father, credited for many good things, to exposed person who really fucked up under pressure, to utterly beyond the pale in quite a short space of time.
Except we do @EdithWeston
Let me count the ways. This will be long, sorry.
He lied about setting up the pap pictures before the wedding, and continued lying even when he was asked about them.
Then, when Meghan and Harry said it was okay, and all would be well, and he should still come to the wedding , he refused to answer their calls, and they found out through TMZ that he was not coming after all.
He then started to blackmail her through the press, his preferred people to talk to being Piers Morgan and Dan Wootton, two of the journalists who had been most horrible about her (long before she and Harry left)
She wrote him a letter, which he passed on to the Mail on Sunday, which published it with bits redacted that would have made Thomas look bad and Meghan look good.
In response to her letter, he wrote asking for a photo opportunity with her, for the media. (He confirmed this in his affidavit by the way)
The whole thing resulted in a high profile court case that was completely unnecessary as it was such a clear case of violation of privacy and copyright. She and Harry believe the stress contributed to her miscarriage.
Her half-sister Samantha sued Meghan over how Meghan felt about her own childhood, and he told the media would testify as a witness against Meghan.
He stated on Piers Morgan that he did not believe Meghan had any mental health issues of any kind while she was in the UK.
He has frequently appeared on YouTube channels that propagate conspiracy theories about his grandchildren, and has discussed whether his daughter had abortions, plural, as a teenager.
He agreed to being flown over to the UK by GB news, and to be hosted by Georgia Colin-Campbell (another person who makes money on YouTube by spreading conspiracy theories about his grandchildren) so that he could "confront" Meghan at the Jubilee. He then fell ill, just as he had before the wedding, and was unable to come.
He, Samantha and the Daily Mail, were the three chief sources for Tom Bower's remarkably vitriolic book.
My working theory has always been that like many Type A personalities, Meghan curated her childhood to present the best image of it. It's interesting to me that Thomas Jr, back when he was estranged from his dad, said he and Doria broke up because Thomas Sr liked to travel to Thailand to have sex with prostituted women. If that's true, that's hardly something Meghan would put on The Tig.
Thomas and his children are beyond defending. Lately, no-one gives them much airtime, so they spend a LOT of time on YouTube conspiracy channels, It's really sad to see actually, Thomas Sr talking about his daughter's frozen eggs, etc, while Thomas Jr, in blackface, pretends to be Meghan having sex with Harry.
Meghan is wise to go No Contact with all of them. I thought Malik Obama, Barack Obama's nutty half-brother was bad. This is next level toxic.
