CS, I am so sorry, man. I really don't know what to say.
FWIW, despite all the pain you're feeling right now, I would much rather be you than your W right now. I would rather be you than OM now, too. You're the one who's grown through this. You're the one who's done the right thing. You are the one going in the right direction. Your W and OM are on the highway to destruction. You're not the one with the guilt.
