G, I think it's good that you want to build a good parenting relationship with her but are you sure that's all it is right now? Only you need to know the answer. The reason I asked was because your goal is to detach so let's say for the sake of the discussion here she decides to move on, finds someone (i know, how insensitive of me) etc. Will you want the same type of a parenting relationship with her that you have now or vice-versa? Will it work?
I'm not suggesting changing anything just curious about your thoughts.
