Personally I'm opposed to them reuniting as its really not in either of their best interests. Rhianna would appear to have suffered the 'battered wife syndrome' and Chris is just a 'batterer' both negative attibutes to publicly display. They are both young and should not have gone so hot and heavy... I mean c'mon they're both entertainers attractive etc. They had time, they should have been mindful of all this. Word has it that jealousy played a major part in their altercation. Perhaps they should just give it a rest.
I think that they should stay away from each other, they just not good for each other, this time it was bad but the next time she may not be so lucky. They should rather move on without each other and find happiness somewhere else.
