My husband has a family commitment that involves traveling by car for 10 hours.  I have a bad back and can't go.  He's totally understanding of that.  It's his weekend with his daughter and she doesn't want to go and he doesn't want her there.  He expects me to watch her.  He says he doesn't have a choice when we does.  I am not her parent.  She has mental health issues, anger issues and oppositional defiant disorder. She doesn't want him to parent her nevertheless me.
