You don't have to agree to a divorce. You can say, once, very calmly, 'I don't want this and I think there are other solutions to our problems,' and then you can do nothing. Step back. Stop convincing him and talking to him about the relationship. Doing what you're doing now isn't working, is it? The man isn't a perfect fit for you if he doesn't want to be married to you and he insists on filming you without your consent.
