I think you're on the right track - lovingly detach, GAL, focus on you again.
As for what to ask - I haven't looked at it recently but maybe re-read the "ask for what you want" part of DR?? I think that's the key.. hopefully your actions will cause him to really "hear" it this time even though he hasn't heard you before.
As to the argument, I think you did fine. Much better that you addressed it rather than stuff it inside and let it fester.
