Is the young man accountable for the sin of the divorce of the married woman with whom he was in contact, despite his attempts to sever the relationship and his knowledge that her husband had discovered the matter?

A man's communication with a non-mahram woman is impermissible in Sharia because it is a means to temptation, whether the woman is married or unmarried. The man must offer sincere repentance. The man does not bear the burden of her divorce; rather, she brought it upon herself through her disobedience and her negligence of her husband's rights. Indeed, sins can be a cause of calamities.
