Hi Natus - Quick question in your updates you refer to your W as stbx. Is that what she wants or what you have accepted as the likely outcome? I only ask as I read your sitch that physical S is still new and that there hasn't been any (as far as I know) legal proceedings to a D.
It sounds great about your positive relationship with your S5. I hope you find that balance of dimness/NC and still able to create a positive environment for the little guy.
