Yeah, while Anna isn't innocent, there always will be the fact that she was only 19 and he mid- to late 20's when they met. They're the definition of co-dependency and we all know how he lets her treat him and his family but instead of giving in to her and completely isolating themselves from his bullies and her worries about being judged or seen as anything less than perfect from the moment they met, he should've known that hiding away from the world together won't make Anna get better. It would do both of them a lot of good to separate for a while and figure themselves out.
But this would very like be the end of them as a couple. He needs her to show off, to show his bullies that he could score a "hot wife", he needs her for YouTube, but does he really love her? Love her as a person and not just as a trophy and business partner? They have nothing in common, no hobbies, no passions. And would she really love him if he wouldn't be the one in a million guy who put up with everything she does, who allows her to stay home all the time, not having to go out to socialise, allowing her to completely indulge in her unhealthy patterns? They're just each others crutches in my eyes.
