Q&A Can I Speak to the Affair Partner in this Situation?

On 14 June 2015 my husband one day told me he doesn't love me anymore. I was devastated.In around April he started to withdraw from me. We had financial difficulties. I thought it was because of this and his father who was staying with us. I then suspected someone else. The woman that worked with both of us in the same office. She was also my friend. She was pregnant at a stage with her and her husband's 2nd child . My husband kept on denying everything ext. On 7 Nov 2016 he at long lasted admitted that they had an affair for about 4 months. It was emotional and sexual. He promised me it isn't his child. We confronted her and made her tell her husband. She stills works with us. I have to see her every Monday when we all have to be at the office. We work through her. We only communicate via email. It really kills me. I feel that there is still information that he isn't sharing.I would have never ever thought he would do such a thing. They both lied so much in that time. We spend a lot of time together outside of work. She told me she loved me and send me all this Christian messages ext. I really want to talk to her and find out the detail that I feel he is not sharing. I know she would probably lie. But I still want to know. She was my friend. Can I talk to her? When we confronted her and thereafter she hasn't once said that she is sorry or showed remorse.
