Re your H's sudden burst of energy... I think y'all have been "in labor" with this separation/D for years. Now that the birth process is happening, I expect to see lots of energy from both of you. It makes perfect sense
I think that this is right. We've already done a lot of the processing that might take place after the divorce in a lot of situations. It's as though all of our "buttons" have disappeared. We're just both very relieved to no longer be working so hard at a compromise with which neither of us felt any level of satisfaction.
