Looks like David and Stephanie slept together. I don't see what the big deal is. I feel sorry for Stephanie that her ex is dragging her name through the mud. Good for David for outing himself before the extortion he's going through was made public by outside sources.
But if he was paying her more just because they were banging or threatened her job in any way, then that's wrong.
