When Stephen was first diagnosed, we weren't actually going out together, but I was already falling in love with him. He had beautiful eyes and this amazing sense of humour, so we were always laughing.
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.
I felt that Stephen had become such a significant figure, a scientist of such international renown, that at some future date, someone would be sure to attempt an inaccurate, sensationalised biography, possibly including me, possibly writing me out of the script.
Intellectually, Stephen was a towering giant. Bodily, he was as helpless as a newborn. The functions I fulfilled were all maternal rather than marital.
