What is the ruling on a wife talking to male friends online to complain about her suffering and her husband's violence, and what is the ruling on a husband abandoning his wife and threatening her with divorce after he has forgiven her?

A woman's conversation with a non-mahram man is reprehensible, though it is permissible out of necessity, provided it adheres to Sharia guidelines. Repentance erases what came before it, so whoever overstepped the boundaries and repented, Allah will accept her repentance. The husband's forgiveness of his wife necessitates overlooking what has passed and not threatening her with divorce. He must treat her kindly. A husband's abandonment of his wife is forbidden unless there is a legitimate Sharia reason. It is advisable to strive for reconciliation and involve wise people. The husband should beware of oppressing his wife or assaulting her.
