Just had a quick re read of some of your posts to refresh me on your sitch and that, combined with your post here today leads me to believe that we are in so precisely the same situation that maybe if we swapped places our spouses wouldn`t notice!
Funny you should mention letting go. I`m getting the same message from my therapist. Also getting to explore more deeply my role in all of this-the split in my personality, my anxiety, my ambiguous behaviour towards my H, my nees to control. Oh and my fear of letting go.
Also found a book today by Melanie Beattie called Letting Go.
Will let you know how I get on with the book. And how I get on with letting go!
