I would say that he treats her like dirt, shit, crap, garbage, whatever metaphor you prefer. He barely even acknowledges her presence. He walks ahead of her in public – this, according to my mother, is a telltale sign of contempt and it is a very bad thing. Ladies any time you are with a man who keeps walking ahead of you, get rid of him. He is doing this because he is embarrassed to be seen with you!
I agree that she displays all of the behavior of an abused woman. He seems to treat her roughly, twisting her finger and apparently ordering her around. He often appears terrified of him. When dancing with him, she looks tense, stiff and fake. But when dancing with a soldier, she comes alive and shows her humanity is yet intact.
Their body language when they are together speaks volumes. It seems like there is a wall of solid frozen stone between them. He never lets her respond and. always talks over her. Even when a question is directed at her and she starts to respond, he cuts her off immediately and takes over the answer. She looks angry when he does this. When discussing what makes him angry, she becomes noticeably nervous and says he likes everything to be done correctly just as he ordered it to be done and gets mad when people do not do their job perfectly.
That he is emotionally and psychologically abusing her is beyond argument. Whether he verbally abuses her or not is more up in the air, but when she is not around, he talks about her in a condescending and insulting way. We also do not know if he is physically abusive to her, although his first wife Ivana charged him with raping her and beating her up on two separate occasions.
