LMNW, I would agree that you haven't really reached the hardest part. Eventually you're going to have to open up some really tough questions...why did you leave, deal with her anger and hurt, etc..
I think you can do it. Your W seems receptive. But if you're really determined, you're going to have to walk through an emotional minefield.
I find that now that my H seems somewhat sympathetic to my situation, I am distressed again and crying a lot, because it means opening up to the possibility of being hurt again.
That said, it sounds as if your W has made it through this part and is starting to trust you again.
