Thanks for the suggestion. That's exactly what I'm going to do if it comes to that. I'm praying it does not.
I will say that I worry that "making" him go to this retreat is seen as pursuing. That if I am supposed to be detaching/letting go, wouldn't I just say, "Fine...don't go. Get out." ???
The other half of me says no, that by holding firmly to the plan of him going is "saying" that I am no longer going to accept his CB and he needs to get on board with getting help. The "or get out" is implied. ???
