The awfulness of the Ghomeshi trial

Did ALL of the women that Ghomeshi supposedly abused so badly later sleep with him again and send him bikini photos and love letters? Or only the three who have testified so far at his trial?
And here I was thinking that police and prosecutors only bring charges against someone when they think they have a winnable court case. With Ghomeshi, they apparently scurried to court with charges that are proving so far to be ludicrous.  Was their goal not to protect women but actually just to display their contempt for the CBC and for Ghomeshi's egotistic celebrity?
I know things have reached a truly awful state when I find myself agreeing with Margaret Wente: The Ghomeshi trial turns into a fiasco:

Everybody knew a guilty verdict was far from sure. The bar for a criminal conviction is, as it should be, high. But nobody, not even the most experienced court-watchers, could have predicted how this trial would go. It has turned into a fiasco . . . .
I know the dynamics of abuse can be complex. I know that women can both love and fear their abusers. But these women were not battered wives. They were not in relationships with Mr. Ghomeshi. They barely knew him. They had no reason to fear him, and he had no power over them at all – except the power of his charm and celebrity. They could have walked away. They didn’t.
And all that’s left is their word about unpleasant encounters that may or may not rise to the standard of criminal assault.
