I plan on it. She hasn't told her parents, who I'm close to, but if I see/hear that it becomes a real problem (I.e. She doesn't agree to it anymore and he continues or he leaves marks) I'll tell her dad in a heartbeat.
Lol I'd never tell them for no reason, that's not my business, but if it gets out of hand, like she's actually getting beaten beyond her will, then you bet I'll snitch.
