I think your response is really strong and sets good boundaries. You have let him know your feelings and are telling him in no uncertain terms that moving out means moving out. This was his choice, now he must live with it.
I hope the DB'ing is getting a little easier for you. You have done a great job so far. All these stressful events seem to pile on top of each other (illness + MLC)... I sometimes think the Universe does that on purpose.
The hardest part of all this is getting to the place where you truly are zen about it - comfortable enough in your own skin to move on and not harbor any ill will. For me, that's the goal, but it's a long scary path.
I'm glad we have this site where we can help each other and provide encouragement.
