What is the ruling on a young man's relationship with a divorced French woman that resulted in pregnancy, and what is the ruling on his marrying her despite his father's objection?

The crime of adultery is one of the most heinous and harmful crimes, and whoever is afflicted by it must repent to Allah. It is not permissible to marry an adulteress until she repents, whether for the one who committed adultery with her or for anyone else. If she is from the People of the Book, it is not permissible to marry her unless she is chaste. Furthermore, it is forbidden to marry a specific woman if it results in the displeasure of the parents and disobedience to their commands.
