I think these are really valid questions - we've all heard stories of women who trusted their husbands and yet were betrayed by them. Gisele Pelicot was one such woman, and her betrayal had nothing to do with her being naive or stupid, and everything to do with the breathtaking deceit and cruelty of her husband. On that basis I accept that there is no way any woman can truly have absolute trust in any man, including a beloved husband / father / brother etc.
The reason I do trust my husband despite this is because over the 15 years we have been together, he had consistently shown himself to be someone who stands for absolute equality and is willing to call out rape culture and patriarchy when he sees it. Not in a showy, grandstanding way, but firmly and quietly. The first time we had sex, during which I was quite clearly enthusiastic and physically consenting, he took the time early on in the process to specifically verbally confirm that I wanted to proceed and felt completely comfortable. He has never once transgressed a boundary. He doesn't laugh at rape jokes and I've heard him tell other people he doesn't find them funny. He dropped a long-term friend for making sexist jokes, and he told him that's why he wasn't willing to continue the friendship. He has never raised his voice at me, said a single unkind thing, tried to control me, believed or insisted that his views, wants, or needs are more important than mine. I've felt cherished and respected by him, and completely safe with him, since the day we met.
I have also experienced none of the physical symptoms or concerns Gisele Pelicot experienced. No memory lapses, blackouts, gynaecological symptoms, sleep issues etc. No causes for any concern at all. One of the immense gifts of Pelicot's astonishing bravery is that women who have experienced these symptoms may be alerted to a cause such as this.
So yes, I do trust my husband, insofar as anyone can ever trust another person. And if he one day betrayed that trust it wouldn't be because of any naivety, stupidity or misconduct on my part. I wouldn't be to blame for having trusted him, just as no woman is to blame for trusting a man who ultimately betrays her.
