I suppose it depends on how you interpret "get off me"
Is she saying "get off me" because he assaulted her? (In my personal experience, I froze when physically assaulted, I didn't scream or shout, but I realise everyone is different)
Is she saying "get off me" because he tried to touch her in a non-violent way, like a partner would to try to de-escalate an argument, and she was angry and wasn't having it?
Unless she comes forward to say she's been assaulted, WE DON'T KNOW
