KGirl and Claire, might I suggest you check out the books by David Schnarch (passionate marriage etc). Sex therapy angle aside, there is so much in his books that speak to the need for personal growth through a process of differentiation. Based on your comments above I think you would find his perspectives useful. It was reading these books that made me realise that DB principles should be a permanent fixture in any adult relationship, not just a short term approach to help us out of a difficult situation.
