I called him, he came home and stuff happened
as long as you still call it HOME when you refer to him coming to your residence, you remain in a mindset that still feels like he WILL be back soon.
and underneath it all, you knew EXACTLY what you were doing. it's like the alcoholic saying "i have no idea how that bottle of tequila got in my hand - except for intentionally driving to the liquor store and purchasing it - but other than THAT, NO idea!!!".
so you aren't totally done yet. face it, own it, deal with it.
