Sinning with a Married Woman

Hello and blessings

A. Since she betrayed her husband with you, you will never be able to marry her. It is completely forbidden.

B. This grave and terrible sin can affect your entire life. The severe harm you are causing the woman's husband is dreadful and awful, and the severe punishment is beyond measure as well. See what was written about a similar story in the book Kav HaYashar, and here are his words:

Know that one incident is brought in the writings of the Ari z'l, that in his time there was a pious man named Rabbi Avraham Ibn Po'ah z'l, and the man was very wealthy and his hand was open to the poor and needy. A Jew lived next to him, and he engaged in business dealings with Rabbi Avraham's wife, since his wife was suited to business dealings. Suddenly that neighbor was stricken with an illness and fell bedridden for many days until his flesh began to rot on him, even his private parts rotted, and he spent a great deal of money on doctors' fees but found no help or remedy for his affliction, and the man died in that illness in bitter suffering. After a number of years, a dog came and would constantly circle the house of the pious Rabbi Avraham Ibn Po'ah. The dog was a very ugly black dog; when people saw it, they were afraid of it because its face was like that of a destructive spirit, and they would always drive that dog away from the house of Rabbi Avraham the pious with sticks, but the dog would return. And every time Rabbi Avraham would rise early for the synagogue, he would find this black dog standing by the door, waiting until they opened the door, and it would want to slip into the house. Rabbi Avraham the pious would always drive it away and instructed that the door be locked after it, yet nevertheless the dog returned and would wait at the door until it was opened. Once it happened that the pious man left early from the entrance of his house and forgot to lock the house door and the winter room door, and immediately the dog leaped into the house and jumped from room to room until it reached the room where Rabbi Avraham's wife was still lying in her bed, and found her asleep. The dog jumped onto the bed and bit her with many bites and wounds, and then fled from the house. The woman cried out loudly until her voice was heard in the house of the Ari z'l. Her husband, Rabbi Avraham the pious, and other people came to Rabbi Yitzchak Luria, and he replied that the reason was because this woman had, God forbid, become another man's wife together with that neighbor who had already died, and this black dog contained his soul. She had been causing that neighbor, through the seduction of her words and by giving him money, to lie with her in a marital manner. Therefore the dog exacted revenge on the woman now. Afterward, they made the woman swear that she would tell the truth, and she admitted that, God forbid, he had been lying with her in the shop, and therefore the flesh of that man rotted, and even his private parts rotted. Afterwards she asked to repent and died in the midst of her repentance, but the pious man immediately expelled her from his house.
