I think your idea about maybe getting her to read DR is a good one - then she can see where you are coming from.
She does have to find it within her tho' to help herself to some extent. It is hard to look at oneself coldly, especially when one knows one is not going to like what they are going to see. Been there and got the T shirt as have most people on here I expect.
Love and support are going to be very important to her I think. 180 is not the same as going dark; let her know you will still be there for her. The fact that you are reading and posting are ways of showing how much you care and want to improve things.
Having someone 100% behind you is a fantastic thing. If you don't value oneself tho' it is hard to believe that someone else values you. You just need to be shown over and over again. I find that I am trying my H out all the time to make sure that he really is 100% committed.
Hang in there.......
