Exactly. People do change but let’s look at the dialogue. He didn’t say ‘I’ve changed my views’, he said ‘Before, you weren’t mrs. so and so’.
And that is actually the same view a lot of Pakistani guys have. They are attracted to one thing but that wouldn’t fly after marriage because then other men might be attracted to that too. Basically saying that the only reason she dressed that way was not because that was her style or what she liked or that she did it for herself but she purely did it to attract men and therefore she shouldn’t now. He’s basically insinuating his wife was slutty before marriage.. so what the hell? why marry her if you had that opinion.
