Lucy was conflicted after hearing the Truth from Rose. She couldn't pass a judgment on what was right and wrong.
After all, Rose's action led to her existence. After a few seconds of pondering, Lucy said, "Still, dad was feeling guilty and obviously depressed too, but he didn't do anything that would ruin your marriage.
While you cheated on him. If your life was ruined because of his… ED, so was his life. Even so, what you did was cruel and inhumane."
Rose nodded slightly and muttered, "You are right."
"And if you truly wanted to start a new life with someone, you could have simply asked for a divorce. Cheating wasn't necessary."
"I had no intention of cheating on Joe. And if I wanted another man in my life, I would have remarried." Rose smiled wryly with a sad look on her face and said, "How in the hell was I supposed to live a happy life while Joe was suffering? Do you think I could ask for a divorce like that?"
