Pretty much. Look at it this way, would you as a DA want to go you trial without your primary witness? It doesn't matter why she is a no show in the end, unless he killed her of course. Even if he paid her to disappear, which is illegal, she would have to still show up to testify to his coercion and bribery. She got what she ultimately wanted in money and revenge for dumping her. He got what he wanted by this all going away. Both parties happy so why prosecute him over a misdemeanor when all involved just want it to go away?
