Very true. It only takes once.I have no idea what did or did not happen between Johnny and his current soon-to-be-ex.
But
I knew three other girls who dated a guy I dated. I believe them when they say he never hit them. He never threatened them. He never raped them. I believe them. But that does not mean he didn't do those things to me.
I admire Vanessa for coming forward (I actually do believe her, that he was never violent to her). However, if doesn't alter whether or not anything happened with anyone else.
But the fact that she threatened him with exactly this (both face to face and through a letter from her lawyer) if he didn't give her everything she wanted pretty much ruins any credibility she had.
