My friend who is a guy let his best friend of 10 years and her kid live with him. She was going through a difficult time and he felt sorry for her. And then she assaulted him in his own house.
She had been living with him since January and a couple of months (in March) he was telling me how she was being rude to him. And how she was treating him. So things escalated and she assaulted him.
I didn't ask him if he went to the police or not. I asked him if he was ok and he said yes.
