I think Chris has a serious mental problem. First of all, men aren't to put their hands or fists on any woman. Those that do, are simply cowards. It's more than just anger issues, because if a man stepped to him, and said something he didn't like, he would think twice before hitting him. He sees a woman as being weaker than himself, and therefore an easy win. Although, what did he really win? The loss of his squeaky clean image, endorsements, money, respect and a host of fans. He couldn't just walk away? With so much at stake?
Secondly, Biting her? Okay, punching her wasn't enough? He wanted to destroy her face, and her body. She's beautiful. Now, I think he must be jealous of her.
And finally, it doesn't matter what was said at the party or in that car,
It was stupid on his part to let it escalate to that level. He's supposed to be a man. Real men don't hit. Cowardly, hotheaded BOYS do.
So he thinks he's a real man? Wait until the REAL thugs see him in jail. Don't do the crime, if you can't do the time.
And yes, he SHOULD go. This is America! Not DisneyDreamWorks. Being rich, does not give one a get out of jail free card, when you do something stupid.
Should they stay together? If she stays with that nut after this one, she needs to have her head examined again. She'll see him go to jail, and have the support of all of her fans, if she remains quiet about this. It's already out there, so all she has to do is sit still. She has sympathy from her fans and supporters. Chris, not so much.
