I'm devastated.

I don't really know what to do. We just I had a miscarriage not long ago and decided we wanted to try again right away. Today is the day I'm ovulating, confirmed in multiple ways, and today is also the day he decided he didn't want to try anymore. He wants to take a break for a year. He made this decision without ever even talking to me. No I have to choose between somebody I loved and somebody I thought I knew, and the thing I want most in the world. How could he make this giant life decision without even including me in the discussion? This is not the person I agreed to marry.
