See this is where it gets murky for me. I believe that they both abused each other. I think her more so because she seems like a conniving manipulative cow, but this case is about her op-ed in The Washington Post where she claims she was abused. Surely, all the proof they need is that he hit her once. Therefore, she was telling the truth. It isn't about who abused the other more, no?
She's already got a counter sue case at the ready, this could take flippin years. At least she's getting the spotlight she so craved.
