"One of the many things confusing me is W's self-described thinking process to arrive at the decision for the D, and W's extreme attitude not wanting to let others know about the bomb."
It's because she wants to remain "in control". She'll blame you for "making" her feel the way she does, but bottomline is that she wants to control the situation so she won't get hurt.
Sandi was asking about the C because, to be honest, at this stage of the game it won't work. We've all learned it the hard way and it's written in DB. I forgot to see if you've read it.
In your W's "moment of clarity", did she say why she wanted a D? I mean real reasons. Is it that she lost respect for you or whatever?
Don't lose hope. First thing you need to do is to stop assuming all the blame of this happening. It doesn't do anyone any good. You can turn the ship around but you have to be strong to do it. I would strongly suggest you go to C just for yourself and DEFINITELY change your username.
If you call yourself "crushd" that is how you will remain. Change it to something more positive and strong. Then believe it and live it.
