At the very least, the husband is a liar, a cheat and a swindler. He sells her this deal "man breadwinner, woman homemaker"... and then takes the friggin home away from her and makes her live in a friggin bus! What a lousy piece'o'crap "breadwinner".
I'm not defending the woman. She could have run away. Anything other than kill her kids. She deserves whatever the judge and jury decide is appropriate for her.
But that husband. What a loser.
