That was an awesome tweet from Rebecca and could be lifted from the relationships board on here, from people who have come out the other side of a bad relationship. Bravo.
I think people who feel invested/disgusted by Seann and Katya's behaviour are likely to be people who have been on the rough end of such behaviour themselves or seen the fallout in the lives of those they love.
I've seen too many people crushed by shitty relationships and betrayal and there's no way I could support them, no matter what bendy tricks Katya pulls off on Saturday. It tarnished their dance partnership in my mind, although I can understand that other people can separate the dancing from life outside of the ballroom.
