Finally someone assessed this observation well enough to infer the over-lining context of Carrie to Natasha than what Natasha was to Carrie. It’s pretty obvious that Careie delt with being a journalist to a magazine editing site for years into her career before she had made it big, and she didn’t get the recognition she got into she had met Big, which jump start her ability to want to prove herself, because she was in the New York space and had been long time friends with the girls with. She didn’t not only come from money, but she had brains and she was deeply educated, as weak as have the privilege to have friends and be herself. Natasha, on the other hand, looks like she has it all, even though she is from a well privileged background ground, she was with Big for a short time before she had divorced him and had remarried, soon after the cheating scandal. So, the thing was, Natasha was envious that Carrie had personality and charisma, while she didn’t, and she had checked every box in Big’s mother’s room for him to wed her and not Carrie, but she felt that she could never truly match up to her, because she’s on the introverted side, which I’ll never understand why people take these things too seriously when they account for these character analysis and self improvement videos. She wasn’t open, and to be frank, she feared actually confidence, despite knowing her worth. She had the ability to stay calm and be honest about her own needs, because she was taught that, but she went in to rush after Carrie, despite not confronting Big about it and/or not evaluating how she’d be hurt from chasing after the spectacle of the adultery right in front of her eyes. People assume that anyone has confidence just because you stand your ground much or have someone rent free in your head wanting what you want, but that’s not the case, since she didn’t either, and knew about the affair and why she chased Carrie, too, because it did upset her and she had no voice to express it and have been keeping it a secret. If she known about it, why chase her or better yet, why not track her in her lies and her husband’s to have done so better? She even expressed how she knew she’d be cheated on, because she was never her husband’s true love, and the reason why he placed her in his wills was because she was marriage approval to the family, and not exactly his type, even though he had taught of her. I have heard countless stories of these contexts, and each gets it wrong, because if a man actually wanted this type of woman as a type, and even if he was childish to not have recognized it, he wouldn’t simply write off who to add to the will, especially not her or Carrie, but since Natasha was more worthy of her lineage, it had to be here. He never cared or loved her, and it was never about his interest to cheat on her with Carrie, because he saw himself de-valuable from his wife, Natasha, to do that, as men do that out of insecurity and disrespect for the woman their wife, but because he liked Carrie, and Carrie wasn’t okay with being the side piece or the mistress. She wanted what both Big and Natasha had and wanted to be with Big, while Natasha felt inferior to the whole thing and wanted peace from it the best way she knew how, by the training she had and from actual experience she wasn’t prepared for.

Problem was, once he got the woman who fit the bill perfectly, he didn't want her. He could not tolerate the idea of someone else being with Carrie. I never understood this ... I do not want you but I do not want anyone else to have you. He should have been happy for Carrie to have found Aidan.

@ you just described a sociopath. I don’t believe was a sociopathI never watched the show, so why I’ve just gone down a binge-watch rabbit hole and only the universe knows why? Carrie’s behaviour is easy to explain, but Mr Big is an enigma to me..well, for the moment a yway
