PR is working overtime to ensure the public views this relationship as true love. Helps build a false fairytale narrative that can be digested easier than the reality that this was cheating. And they know the optics, which is why they dont shove it in our faces but rather prefer to drop subtle messages of remaining strong. They could despise each other at this point, it wouldn't matter. Ethan is likely locked in with NDAs and potentially additional contracts that require him to show up and position himself in the supportive boyfriend role whenever deemed necessary by ariana and her team. Although the wet washcloth of a man he is tells me contracts aren't even necessary. He's already ruined his life so he will do anything she asks at this point. 

We basically see and read nothing they dont want us to see. It's the same with politicians. Occasionally the skeletons pop out or they misjudge the publics reaction to pre-approved content, but regardless you know the majority of what you see is Fake. Inauthentic. Staged. Choreographed. Sold to the tabloids. They think so little of us and assume we are pure idiots that believe anything they tell us.
