Gerta is an Abuser, she ‘owns’ her husband. She controls where he lives, what he does. He goes where she allows.
He can not work in her country until he learns the language, so has to spend years to become fluent so as to be able to work.
To work would mean he would have his own money, he wouldn’t have to depend on Gerta.
However, it has been a dozen years since she bought him. She does not want him to work. His choice; would he give up the 1st World 1st Class life he has become accustomed to?
It is very unlikely Rick can ever escape Gerta.
He knows what he is. He knows and it hurts, because once he was independent, well thought of, popular. Now, he is nothing but Gerta’s property.
Escape is unlikely.
