Before. I would think it could have gone down like this:
1. Zeke wanted out of the relationship; she didn't. Argument/fight ensues, words escalate to physical action -- battery.
2. She is a jilted lover and decides to try to ruin his life/NFL career.
3. After discussing same with her friend, they get the silly/stupid/etc. idea of attempting to blackmail him, as another avenue of punishing him.
In this scenario, both parties are bad actors; neither is blameless.
