Ah, your old "you know you are, you said you are" gambit. You do that a lot.
I'm not saying they were editing it with any specific agenda, but something being edited necessarily means you're not seeing the whole thing. And of course that means something. Like how when I watch a few highlights you tell me I'm not seeing the whole game and therefore you know better than me. Curiously you also seem to know better than other people who watched the game.You said edited as if that means anything. Answer me this, why would it have been edited to make him seem worse than he is.
But the point is Mrs Arteta appears for a few minutes of the whole series. And from that and some brief interaction between them in front of cameras, which necessarily changes behaviour anyway, you think you have some insight into the state of their marriage. It's laughable, honestly.
LOL @ you calling anyone else arrogant. As Oscar Wilde, or possibly Simply Red, once said "look in the mirror baby".
