I may not have been in abusive relationship or marriage, but from what I can tell about abusive situations, I can understand why Lucy at first said no to both punishment and divorce of her husband. She most likely said that as she still feels the love he had when times were good but after experiencing it from a different perspective, she didn't have the heart to continue with her marriage and finally asked for a divorce by literally one of the most powerful people in the Empire who has great connections.
She deserves someone like Joseph who is pure hearted and the type of man to be a loving husband for Lucy.
