Four years ago my husband and I separated. But I didn’t seriously bring up the subject of divorce until we met for coffee just before Christmas. We had sorted out our finances in the interim, so there had been no pressing reason to go for the decree. “Up to you,” he said casually. And then, eyeing me quizzically: “Not planning to get married again are you?” He knows I live with my new partner. I replied in the negative. “Well you look into it and I’ll pay half,” he said, before picking up the bill for my scrambled eggs.
