I have a question. In an interview, Gillian said she’s grateful for the symbiosis with PM because she had never been with a man working in the industry before. Don’t you think it means she’s never been with David then? Genuine question!

I guess you can take it that way. But that would mean she’s never been with her first husband either who she literally met on the set of XF amongst the crew members. Or that she’s never been with Rodney Roland, who she also met on the set of XF amongst the cast members. Or that she’s never been with her second husband who was a producer / director.
I remember this interview, but you never know if it’s really what she said or what she meant. Either ways, it’s not true.
