You are still in the shock stage, and that's normal. Heck 3 years post BD I still shake my head and think "Really .. this is what is left??" but as with all these things it cycles and is less intense with each rotation.
So your W is filling out D papers, that's what she thinks will bring happiness and there is not much you can do about that. Listen to your parents because they are correct, at this moment its business, protect yourself and the kids and remove the emotion out of it the best you can. Focus on yourself for a bit ... its time to start the mirror work.
