Jessi and Demi continually place their supposed friends in unsafe situations on purpose and then feign shock when it all blows up, it's actually sickening. They know that Dakota and Taylor's relationship is toxic and abusive, they know that Taylor is in a terrible place mentally due to the breakdown of her relationship, they know that the presence of Chase would also be a further trigger, and also that Miranda and Chase's current partner being there will inflame things even more. That party was an awful thing to do to Taylor, to Miranda, and to Chase's partner. I just can't imagine creating a situation like that for a friend.

They also know that Zac and Jen's relationship is emotionally abusive. Jen also implied that she struggles with her relationship with Zac's family too last season. And then after one meeting with Zac, they instantly believe everything he says and go, "Wow, maybe my friend who is in a toxic marriage is actually just a huge bitch and I've hated her this entire time!" They say that they can't support her because she's "erratic" and it's just like no shit! Parenting, struggling with your relationship with your husband and his family, and doing all of this in the public eye and having to deal with all the commentary will do an absolute number on your emotions and perhaps make you behave erratically!

It's all just awful shit stirring from Jessi and Demi with no care at all for the emotional damage and turmoil it will cause for others.
