Found this HuffPo article about emails Susan Powell sent to her family, friends and members of her church before her disappearance. She talked about how controlling and moody Josh had gotten, and how she was afraid of him, and asked for relationship advice. She said he had changed since she married him and she thought he needed both counseling and medication, and spoke of leaving him:
I know everyone else will support me in whatever decisions, even if that means I crash anyone’s house in the middle of the night with my boys in tow. (Hope that never happens)
But at that point she believed the marriage was still salvageable:
I’m sure if he fixes himself, everyone else will see a much closer version of the guy I married. And it will be easy enough to forget the hell and turmoil he’s put me through.
I suppose the people that got those emails are now beating themselves up for not begging her to leave him earlier. But I think Susan’s friends and family did the best they could for her. The problem was, Susan was a grown woman and no one could force her to leave her husband, and Josh was just too evil and too manipulative. If he was bipolar or whatever, meds would have helped, but all the counseling and medication in the world cannot fix a psychopath.
