That is a fair question. But I think that would reflect rather strangely on her, dozens of hetero relationships but she shies away from even one non-het relationship?
Anyway, that is one of the few theories offered so far that I can KIND of see as an excuse, if I squint real hard. So thank you.
On the other hand, she did just write a research intensive spy techno-thriller, I’m told. If she can research one of the toughest genres going, why couldn’t she research a relationship she herself thought was important?
