I try to remind myself of who we are now and why it’s best that we are over. I think about the day he asked me for a divorce. Aug. 4, 2009. Just two days earlier, I had left for Warsaw, Poland, on a two-month research trip for a book I was writing. It was one of the few times in our relationship that I had done the leaving. I always feared that if we were both bouncing around the world for the sake of our careers, we’d never last.
