I have always warmed to Nadiya.
She’s got a dd and is engaged to her her parter and I’m sure when she does SCD her family are not in the UK, so that must be tough.
She very rarely posts a picture of her DD on social media (Insta) and if she does, it isn’t her face/identity. She always gushes about how much she loves her.
I think she sees SCD as a job, it earns money post professional competitions and she goes back to her home life afterwards.
As PP said she’s had some shit dance partners in the past and has probably been welcomed in to the Walkers - they have the same values (solid partnership, children, doesn’t make kids a cash cow) and she has really enjoyed that side of things, and the friendship.
She also doesn’t do the shows that some of the professionals do post SCD (although I have seen her on SCD live) which to me implies she goes back to her home town.
