Should a husband divorce his wife who is addicted to watching pornography and chatting with men online, or should he try to reform her first?

Watching pornographic movies is an act of disobedience and sin. If this is coupled with talking to strangers [of the opposite sex, in a manner that is not permissible], the sin becomes greater. The husband should guide his wife if he becomes aware of her committing these forbidden acts. As for divorcing her, a comparison should be made between the harm of divorce and the harm of her remaining [in the marriage while continuing these acts].
