I'm sorry, but I just don't see the basis for making judgments about someone "famous" based solely on whatever has been reported in the media.
The only two people in this situation who know what really happened and what's really going on are the two people in the relationship. In this case we're talking about two very young, famous, and monied people. With all the publicity surrounding this case, I'm quite certain that Rhianna has been inundated with "advice" from those looking to be helpful who have simply no idea what they're talking about.
I'm not condoning his actions in any way shape or form. But statements like these:
Anyways.. She says she will not testify against him. I am assuming that means she might be back with this jerk, or she has sympathy for him. I think her family or friends need to step in and remind her that he didn't care while he heat the "crap" out of her.
make a series of dangerous assumptions about the situation as well. What if there is enough evidence against him that there is no need for her to testify? What if testifying would cause her more emotional trauma? What if she's been counseled by her legal team not to testify for fear of incriminating herself somehow? How is judging that bit of information one way or the other productive?
We don't know them or their relationship. Inevitably we color our view of what's going on through the lens of our own personal experience. We're also talking about someone who certainly has the resources and likely now the education about domestic abuse to make an informed decision, but is young and famous and rich with all the trappings and pitfalls attached.
We've all made our own decisions in our own lives that might not have been the best for our mental, physical or emotional health. Why should one person be pilloried for the same kind of mistakes (if it indeed turns out to be true and a mistake) that we ourselves have made simply because they are famous? Being rich and/or famous doesn't get you out of being human - and that applies to both people involved here.
