One thing that I would advise, is that you don't try and diagnose every small detail of what/ and why she is doing this or that.

You've had a major shock to your system, and no matter how much things make sense today, in ten minutes you will be asking the same question and trying to find the same answers over and over again....

EVERY thing, every decision that you make now, will be an emotional decision. Your spouse is running on pure emotion right now, and there is NO reason for you both to be doing that....

So "thinking" isn't quite as important than making sure that you are taking care of yourself. And getting yourself to a calmer, more rational mindset...

Eating right, SLEEPING, working out, etc....
