Also they should look at the sports study of concussions and brain injury.
I am reading some of the coverage of Chris Brown's abuse of Rihanna and everyone piling on her for reconciling. No one gets why it's so difficult for her to just walk away. That's because no one but her is in a relationship with him and in love with him. Without that emotion, it's so easy to see that she should leave him.
I'd like for her critics to imagine that suddenly the person they love hits them several times during a heated argument. I'd like for them to imagine the shock that this person they love is behaving this way. Those who say there should be a zero tolerance policy should imagine this. Imagine walking away from the person you love, the person who previously gave no obvious hint they'd ever do this. Imagine that person crying as they express remorse and promising to change. This person you love, this person you've shared so much with, this lover who is crying over having hurt you so badly. That angry person who hit you seems like an aberration. Surely this lover you've trusted with your heart and soul, who has been kind to you when you were sick, who has supported you in so many ways, this kind person is the real person, and will overcome the anger. Your love softens you and you agree to give them another chance. Everyone deserves a second chance, right? It's only fair.
Love doesn't stop on a dime. It takes a lot of beatings to kill it completely.
