Taubah and Repentance

Q:

1. If someone had unlawful acts/relations more than one time/many times, with his married paternal aunt (father's sister) and then with the same paternal aunts' daughter in law (son's wife). Also with same paternal aunt's daughter. His actions were such that perhaps hurmat maybe established, meaning anything but not actual zina. He is a single adult and lives away from them. What is the status of the marriages of his marries parental aunt, the same aunt's daughter in law and the same aunt's daughter? He has asked someone, and being told all of them's marriages are still valid.

2. Also, how to repent in this case? Mufti Taqi Usmani says, you can seek forgiveness from Allah Ta'ala by making sincere repentance, then you should have hope and forget your past sins, trust Allah's mercy... Allah's mercy is so vast, he can and does forgive any sin, no matter what.

Q: I have a friend who entered an unlawful relationship about 7 months ago. She ended the relationship after two months due to the guilt. She feels very impure and cries a lot about her sin. She claims to believe in Allah's forgiveness, but is unable to bear herself. She breaks down a lot and feels like she is no longer a good and pure woman. She also feels like it is wrong to put it behind her. Is it possible that Allah has wiped away her sin and purified her?
