The thing is though, thats only the case because of her celebrity status, women all over the world take their abusive partners back everyday, the only difference is, its not publicised. Just because she is a celebrity doesn't make the decision to take Chris back any different, it just means the criticism she gets will be more global and more widespread. It's ridiculous to think she will be punished in the public eye because of this.
Women who have been abused more often than not feel as if the abuse is their fault, and they have so low self esteem that they think the abusive relationnship is the only form of love they can get. So in part it becomes acceptable. The last thing Rihanna needs right now is everyone who supported her throughout the situation, now turning their back to her because she took him back. Thats not gonna do anything positive for her lack of self esteem.
