CSan, for what it's worth, I personally know several couples who got remarried after the divorce (one in my family).
I would DEFINITELY not move to undo the separation and the divorce is out of your hands so revisiting just to see where things are between you is an option that doesn't really have any consequences, right? The most you have to lose is some time with the MC.
You mention fearing new hurt. Are you still hurting now? Do you sense change in him that would alter your ability to feel at peace?
On other threads a lot of spouses say they NEED the divorce in order to address the issues in the M. It doesn't sound rational to a lot of us but it's true for them. Is it possible that your H feeling free makes it easier for him to address things with you, he doesn't feel trapped so he is more honest?
But the question stands: What do you WANT?
