I mean, she did call 911 on him several times and file for restraining orders because of his abuse of her, so she minded that. It’s not a stretch to say she minded it enough to not want to cross him.

Yep, her abusive ex-husband, whom she tried to leave, but was told to reconcile with if she wanted to make the Olympics.
