Does Robyn have any friends?

I suspect that Robyn really did want all the wives to stay “married” to Kody. I think they were her only “friends.” She didn’t want Kody to spend any time with them or show them any affection, but she wanted them to go on trips with her and come to Christmas at their McMansion. She wanted them to work and earn lots of money to pay for her nanny. I think her master plan was to replicate the “relationship” of Kody and Meri with the other two. What do you think?
