Is the questioner considered sinful for offering advice to a close female relative who is experiencing marital problems with her husband that would justify divorce, and would he have a role if a divorce were to occur, and is there expiation or repentance if he is sinful?

"Your advice to the woman regarding her marital problems is not sinful. However, your calls to her and your discussions with her about your mutual feelings are sinful, and it is feared that this may be a cause for increasing her desire to separate from her husband. Therefore, you must repent by ceasing these calls, regretting what has passed, and resolving not to return to such actions."
