She was shaking the kid and calling him stupid and to shut the hell up, along with shaking him and pulling his hair. Told her to stop or else I would report her. She stopped but I can't get that image out of my mind, that anger she was displaying.
Before this event happen, I though she was the girl I was glad to present to my family, smart and the one I would consider marriage in the future. Now I don't know. She claims to be very sorry and that nothing like that would happen again.

If I were you I'd ask the child whether she has ever been rough or violent to him before, and also keep an eye out for other violent behavior from her in the future.
If she really has never done anything like that before, then it could be that she was just frustrated with the child, especially if he/she has been really difficult. Even good people can lose control sometimes and do things they normally would never do. But if the behavior is repeated, then it would be clear that there's a problem. Either she doesn't think it's wrong to get rough on a child, or she loses control very easily. Both dangerous.
