As for Dijana, add to that the fact that they lived with her parents in her home country. If she was stuck in the UK with no immediate family or anyone outside the religion, and JWs giving her shit if she tried to leave him or tried to leave the religion with him, I might understand how she would feel trapped and had no place to go.
But she's back home, with mommy and daddy and other relatives. She could probably even get the authorities involved if she knew he was dallying with prostitutes. Plus she has two young girls to think about.
So something is definitely off with her.
