Peter/Sandra is a terrible person who used a woman as cover, cheated on her, emotionally neglected her, manipulated her into swapping spouses (trafficking) to try to keep the marriage alive, then financial and emotionally abandoned the children.  I get it, hurt people hurt people, but that’s not an excuse.  Go to therapy and take care of your responsibilities.  When asked if there would be or ever was an attempt to find the kids the response was basically “forget that!  It would be hard and complicated and other people might have an emotion and I might have to take responsibility so no way!”

Despicable person.  I get that the job is to clean up the messes of others, and maybe in some misguided manner that is an attempt to make amends with the world, but that does nothing for the people that were injured by continued neglect.
