It's funny you mention that about her childhood because I just picked up a new book on codependency and love addiction. I started to read it and it described so much about my W and it talks about how it starts by things in their childhood. I realized that there were two major things I know that would have done this.
One thing I know is that even though that I understand it I do not know enough about it to be of much use let alone be able to help her recover from it.
What I would do is not discus it with her because it is just the male mentality trying to be mister fix it when women just want to be understood. I would just show empathy and be understanding if it is brought up by her. Just remember she is in a very delicate state right now and does not want to be fixed by no one.
Love is a decision. Genuine love is honor put into action, regardless of the cost.
