I don't think it's appropriate to assume that if a woman is doing evil shit, it's because her husband is making her. That's before considering that this guy and his family both openly admit to him basically refusing to leave his bedroom for days at a time.

There's that profile story that came out where Fetterman was driving erratically with his family trapped in the car with him.

So yeah I'd believe that she's trapped with someone who looks like her husband but isn't her husband anymore (due to the stroke)
