Man, you just can't win with these kinds of stories. If the living spouse commits an hero to "join up" with the dead one because they've based their life around, and defined themselves by their relationship with the dead spouse, then that's a tragedy. On the other hand, if they move on and someone else then that's sad for the readers who want to see the dead spouse be happy with the living one, and not wanting the living spouse to get over the dead one enough that they can "replace" them and not think about them again
