She was very busy
By the time Meghan asked Catherine for help, she was pregnant with her third child. Meghan wanted me to help her and give her advice on how to fit in, but Catherine said that guiding Meghan was not on her Real agenda, which she already had enough with her children and her royal duties. It is true that she was really very busy but Meghan felt despised by her, by the way she answered her.
The two came the same
The two Duchesses were the bedside table of the press day after day. There was no magazine or newspaper that didn’t talk about them and their possible bad relationship, whether they hated each other or not. Even when the two women came from families without noble blood, there seemed to be an abyss between them. Catherine, for her part, adapted quickly and well and was also welcomed into the family without any qualms, but why didn’t Meghan be accepted? Perhaps because she’s an actress, or an American or an African-American.
