How did she end up with a mutt like him?
I agree with you. She seems as though she had a decent career and then she married him, someone who was washed up and needed someone to give him visibility. He has done nothing but use her and ruin her career. Maybe a combination of personal incompetence, jealousy, even hatred? Very, very weird. For all I know, with his contacts (whoever is supporting his lifestyle) could be threatening her lest she tells what she knows. I have no idea... All is not, though, as it seems.
