Through singing, I met my second husband, Jonathan, who is a professional musician. He transformed our lives and relieved me of much of the strain that I had been carrying for so long.

Stephen could be highly critical of people other than his closest relatives... He considered my friends to be easy victims and had no compunction in monopolizing the conversation at parties with his controversial opinions.

I suppose I was still optimistic and unrealistic, and I just hoped we could keep going as we were. But no. That was not good enough for Stephen, so off he went. Those were hard times. They really were. But then, I suppose, divorce is always hard.

We would look up at the night sky together, and although Stephen wasn't actually very good at detecting constellations, he would tell me about the expanding universe and the possibility of it contracting again and describe a star collapsing in on itself to form a black hole in a way that was quite easy to understand.
