I think Anna's been conditioned to think that Jonathan is above her. For all she mocks and talks down to him at times (resentment perhaps?), I think she's been manipulated to think that she owes him. In order to sustain the lifestyle she wants, she has to put up with it and shut up. Jonathan's all about image - that's why I think one of the main factors in her ED struggle is her trying to maintain the 'look' Jonathan wants for her. Jonathan's also all she's ever known, really - she was 19 I believe when they met? This is what she believes love is. We've seen how much she idolizes her father and how outdated her views are, like you say - to her, a wife's duty is to accommodate her husband. It's common for people to mirror their own relationship with how they perceived their parents' relationship to be growing up. I could be very wrong, obviously - but it looks to me that Anna doesn't really love Jonathan (she just thinks she does as she doesn't know any different), and she'll go along with anything he wants, even if she doesn't necessarily agree with it, as she believes she can't function without him.
