I think that it is a dangerous assumption that keeps LBS from moving on. The whole idea that a spouse is "in a fog," "not themselves right now," or otherwise "insane," just because they don't want to be with us anymore.
Were they insane to be with us and not their previous partners? I don't think so.
It is a very rare thing for couples to stay together, "happily," after the initial rush wears off. Most humans don't really want the depth and comfort of longevity. It's boring to them. They want the excitement back.
I believe that most relationships simply run their course and that is all there is to it.
