Hmmm...I don't know GD, sounds to me like Heim WANTS his wife back too.
I suggested the letter so that he could actually LET GO, like you suggest, of the things he is harboring STILL, which does not help him move along, GAL or other. Maybe you should write it out anyway Heim, and then burn it, and then have a happy letting go dance around a bonfire. Since I'm sure with your frustration level it would be a HUGE fire.
