Correct. The term "poly" is just a way of dismissing being a whore as "we're actually open". If you go back on their videos you'll see that he was actually the first one to fuck other girls. That must have been the honeymoon phase he got to enjoy before the real reason sank in. Now she's getting ragdolled by other men and her husband barely features anymore. And when he does feature, it's only with her. Funny how the "poly" thing only goes one way now.
She's exploring her breeding kink with other men and soon it will be legit creampies and at that point I believe they will be done as a couple.
Imagine how emasculating it must feel to watch your wife go from "I respect my hubby and save things just for him" to this.
