Patt, we LBSs tend to overthink everything, and that's what you did here. The mistake, to me, wasn't staying the truth. The mistake was being so engaging with him to begin with. You said he came to cook dinner because you are still out of commission, but then say you cooked together? So which is it? If he is there to help then stay out of the kitchen and let him cook!
Don't start conversations and don't initiate affection. And certainly do not apologize when you tell him the truth! He did walk out. So what if that made him angry? Remember, you can't nice him back. There will be times when for are properly DBing where he will become angry. Because in DBing you're taking his cake away. But that is the only way he'll consider coming back. Because right now he is living the dream! Freedom but still gets to play house.
The other thing about DBing, no one does it well at first. The key is to learn from your mistakes. So learn from this. You're engaging him too much, so stop that. Don't apologize when he gets angry. Those are your two biggest learnings right now.
