In response to a 2012 article, Gillian Anderson wrote,

It was the first time I revealed this fact in a public forum, and I chose to do so for two reasons. One was that a woman whom I was in relationship with had died a few months beforehand and I felt, in the context of our conversation, it was safe and appropriate to bring it up. Many years beforehand, and well beyond our time together, this woman had called me out of the blue at the height of my television fame to say that she had been offered $60,000 by a tabloid to provide a picture of us together. At the time, for various reasons, not including shame, I did not want that information in the public domain and despite the fact that she was struggling to pay her rent, I asked her not to sell our story. She took what at the time I considered to be the high road. To this day I regret asking her to do that. That 60 grand would have had a greater positive effect on her life than a negative effect on mine. By discussing our relationship in Out, I felt like I was honoring her memory in some way simply by admitting its existence.[1]

Gillian Anderson went on to say that she is certainly not gay and ended by saying that she wanted, 

...to share once, and once only, the fact that a seemingly straight-laced almost middle aged woman with three children can be open and shame-free about her life and love experiences and it’s okay.[2]

In 2015 when asked if she would be interested in having a same-sex relationship again, she told The Guardian

I wouldn’t discount it, I did it before and I’m not closed to that idea. To me a relationship is about loving another human being; their gender is irrelevant.[3]
