Did she become upset with him when sex didn't advance her writing career?
Yeah, it is a vast conspiracy so far involving 15 women and a republican DA, and that is why the DA believed him guilty in 2000 and why Cosby settled on the 2004 case when so many women were willing to swear to his attacks on them.
It is also why his attorney just corrected his official statement from a few days ago.
It is also why he was bluffing when he threatened the National Enquirer with a 250 million dollar lawsuit and they met it with the threat they would counter sue.
