Good call on the 24 hour rule. Regardless of what happens, it seems that your rollercoaster is likely to accelerate a bit over the next few days. Try to keep that 24-hour rule in mind if you can so that you can keep a lid on any rash decisions or knee-jerk emotions. You've done very well to this point. I'm sure you'll do fine.
I'm trying to think back a bit...to put myself in your situation...
A couple of things to remember:
1) You are okay. It *does* take two for a R to get to this point but you've done your best. You might be tempted to do the "if only I had done this" thing...everyone makes mistakes along the way and it's even more difficult to be perfect when there is such emotional turmoil involved.
2) Very important..."three breaths". Who knows which way things are going to go now but, coming from someone who can tell you what *not* to do, the more under-control you can remain for the next few weeks the better it will be for you. It's silly and simple but taking three breaths before reacting to any news...good or bad...can be a great tactic to keep your head and prevent you from saying anything extreme.
As others have said, regardless of which way it looks like your H is going to go, you should probably be preparing your finances.
