I don't know if that is Dijana in the photo.
As for Evans's income, I assume he is providing for the girls, at the very least. I might be giving him too much credit, but just for appearances (which matter massively to him) I would expect him to be sending them something each month. Still, he should be making enough to get by. But no one wants to simply get by. And 'getting by' doesn't include indulgences like buying sex.
He doesn't want to make enough to get by. I think he feels he was on the way to some level of stardom, of being somebody. Making a relatively comfortable living must feel like a slap in the face. The mind-boggling thing, after all this time, is that success is still ultimately in his hands, but he simply isn't capable of humbling himself and putting in the necessary work. On the other hand, the idea that he is the architect of his own humiliation and downfall is very fitting.
