In episode 12 of season 7 of «90 Day Fiancé: Before the 90 Days,» Vanja and Bozo had a major argument while he was out with his friends. Vanja expressed concern about the lack of intimacy and romance in their relationship, but Bozo claimed that everything was fine.
This led to an argument that created a rift between them. Bozo suggested that Vanja spend time alone instead of hanging out with her family, which shocked and frustrated her.
Vanja thought that Bozo didn’t reciprocate her feelings because he was still in love with his ex, but she found out that he had no contact with her, which made her question his motives.
