Forgiving Herself ...
Livvy: Once you told me that this is a beginning. But how do you know, Ray? How do you know it's the beginning of something good?
Ray: I know. Because someday, you're bound to forgive yourself.
I've read the book a couple of times since the movie and will no doubt read it again and again. There's something that bothers me and I am trying to figure out what Ray really meant when he said that Livvy was bound to forgive herself someday. Forgive herself for what? Her past indiscretion with Edward?
Of course, Livvy wished she had never let herself be swept away by Edward. However, what bothered her the most was that she wouldn't be able to live her life as she had planned it. Throughout much of the book, she plans how she can at least finish her degree and teach and go on local digs. A child would prevent her from going to Egypt but she didn't want to give up on all her dreams completely.
So, I don't think it was a matter of forgiving herself or not.
In the book, it was clear that Livvy was not attracted to Ray. In fact, she would remind herself of his faults. However, Livvy didn't want to lead Ray on as Edward had lead her on. When Livvy would tell Ray he was a good man .... but she was not the right woman for him ... it was not because she had low self-esteem or felt unworthy because of the Edward incident. It was because Ray was the total opposite of Edward and there wasn't a mutual attraction.
So what did Livvy need to forgive of herself?
