Sister Wives is about to start its seventeenth season, and in a new clip, Christine Brown can be heard calling her ex-husband Kody Brown "cowardly"

and telling him to "man the f— up." In an exclusive clip that Entertainment Tonight shared,

the two people who are no longer together can be seen arguing about their relationship.

"Why are you holding on to me so hard? Kody, this doesn't work. You said it wasn't working either.

" At one point in the conversation, Christine tells Kody.

She goes on, "You said you were not interested in me. You didn't want to get married to me in a sexual way.
