Julie, in the worst case scenario, are you in a good legal position to take care of yourself and your kids?
I sense a fear in you that H is trying to put you at a disadvantage finacially. That is a very valid fear. If you have your cards right, and keep them close to your heart, would you feel less fearful? Should that be the case, then you could do what you need to do to keep that fear at bay, so that you can work on the R with fewer reservations.
It will be good to have that in place before you investigate your doubts about the A. Because, even if you feel mentally prepared, a confirmation of your doubts will send you into a tailspin. And if your fears are true, have you thought about what you are going to do? You say that an A is a dealbreaker for you, but would you be so sure about your feelings once you start the D process rolling?
Just food for thought.
You can call me Dory/ Grl.

It's no use to go back to yesterday because I was a different person then.
