Will the girl accept the young man who betrayed her and got another girl pregnant, or will she leave him to God and wait for another groom?

The wise person chooses a life partner characterized by religious devotion, as stated in the Hadith: "A woman is married for four things: her wealth, her lineage, her beauty, and her religion. So, choose the religious woman, and you will prosper." And His (peace be upon him) saying: "If there comes to you one whose religion and character you approve, then marry him. If you do not do so, there will be tribulation on earth and widespread corruption." Therefore, it is advised not to accept a young man unless he avoids sins and his sincere repentance and steadfastness in performing prayers are known. For a righteous husband treats his wife well, unlike the irreligious one whose companionship is bad and who wrongs his wife.
