I actually feel very sorry for him, and I don't think the antics of his past two years are a reflection of his arrogance or his narcissism (Which there is definetely an abundance of)
With many players, you see they have lots of interests outside of playing football. Businesses, things to do, shiny toys, 10 SUVs and tweaking performance vehicles for fun, partying, punditry, restauranteurs, property empires etc.
All Ronaldo has known, and all he has ever known and seemingly wants to know, is football. He's practically a billionaire, and most of it liquid too, and what does he do? Eat the most bland, perfectly balanced diet every single meal, every single day. He has a giant mansion...that he mainly utilizes to keep himself fit in the best way possible. Giant swimming pool to relax with friends and piss around? No, it's to warm down after training. Does he go out partying? Nope. Drinking? Nope. Any debauchery that might affect his football? Nope. And he's 40 years old at this point. He has a giant car collection of supercars and yet seemingly doesn't give a shit about them.
Since he started football at a young age, he's been obsessed with it and gave everything else up for it, for his entire adult life.
I think he's desperate to still perform, to still play, to try and prove to himself and the world that he's still got it, because I think he hasn't got a fecking clue what he is going to do after he retires from football. That's why it upset him so much that they lost the Saudi league - it was kind of a reality check for him.
He probably needs someone to sit him down at this point to be honest.
