I can feel your pain and anxiety. The stress of trying to figure out what to do to get the results you are after takes its toll. I wish I had let go sooner than I did, but I felt like you, and knew if I didn't hold on, he certainly wasn't going to. My DB Coach though explained to me although, that is a natural feeling to have, it is counter-productive. I wish I had detached sooner. At this point, you will have to "act as if", as if you are thinking about what he needs, and if what he needs is to leave, you won't stand in his way, and that although you wished he would not leave, you are being understanding, and loving about his decision. It takes away his reason to struggle against you.

Believe me, I am not a expert, just someone who has been there. I do think the DB Coaches are so worth it if you could talk to one of them.
