I will never forget the exact moment my marriage died.

Derek Whitmore ended our marriage on a Tuesday night.

He sat across from me at the kitchen table and spread six years of my fertility records between us like a prosecutor presenting evidence.

Then he leaned back and smiled.

‘Madison’s pregnant,’ he said, casually fixing the sleeve of the expensive suit I had helped pay for. ‘So I suppose we finally know which one of us had the problem.’
