However, she and Prince Harry spend most of their weekends at their home in the Cotswolds in a bid to stay out of the spotlight, according to the insider.
The source said Meghan was finding it "tough" to trust anyone outside her new royal circle.
But apparently, Meghan is setting her own style rules.
Meghan has two dogs - a recently adopted Labrador named "Oz", and a beagle called Guy.
The 37-year-old Duchess of Sussex spent most of her life in Los Angeles before moving to Toronto to film Suits, where she lived for seven years and built a network of trustworthy close friends, most of whom were fixtures in high society so were already familiar with the precariousness of public life.
She no longer speaks to close childhood friend, Ninaki Priddy, who was the maid of honour at her first wedding to Trevor Engelson.
The debate continues online as to the validity of Meghan being out and about with her dog without any apparent security.
"There's a small group of us that check in with her and see how she's doing, but she's still the same person", Martin told the magazine. "The beginning of marriages are not that easy, but to have that impetus of your own family being disloyal is terrible and embarrassing". The DUCHASS should be humane to our father who has given her everything ... and this media crap can stop! Once she decides you're not part of her life, she can be very cold.
Just this week, Meghan's sister Samantha took to Twitter to coin a nasty schoolyard nickname for her and attack her yet again. "It was something she dreamed of as a girl when we watched the royals on TV".
"I think on her wedding day she just wanted to be herself".
