The 38-year-old actress starred opposite Dominic West in the hit Showtime series for four years before leaving amid reports of a toxic work environment and too many sex scenes.
Wilson has now spoken out for the first time, telling Stylist magazine: "The reason I haven't gone into The Affair is that I haven't worked out how to discuss it.
"There's a lot of noise and anger surrounding it, and really the power rests with me to choose how I discuss my life and my experiences.
"What's important to say is that I did speak up. I did have a voice. I did stand up for myself. There was a situation on The Affair where things didn't feel right, and I dealt with them, and I managed to protect myself."

Ruth Wilson attends the Philips British Academy Television Awards (BAFTA) at London Palladium on June 6, 2010 in London, England.
A source with firsthand knowledge of the production told The Hollywood Reporter: "There was a culture problem at the show from the very beginning and a tone-deafness from Sarah Treem about recognising the position she was putting actors in.
"Over and over again, I witnessed Sarah Treem try to cajole actors to get naked even if they were uncomfortable or not contractually obligated to."
The Affair also starred Dominic West, Maura Tierney, and Joshua Jackson. Anna Paquin joined the show for the fifth and final season after the departure of Wilson, playing her character's daughter as an adult.
