<human>: Condense the text into a few key points

Last year, I (24, F) had a six-week long affair with a married man (30, M) while he was in the middle of being away from his wife for six months.  (they saw each other about once every two weeks.)

I know, this is terrible of me and I am a terrible person for sleeping with him.  However, I felt like it was his responsibility to be faithful to his wife, and I wasn't interested in a serious relationship with him anyway.  Still, this is not a moment in my life I am proud of, so I hope you can see why I don't talk about this with my friends.  

Anyway, from the outside they are a perfect couple and we have many mutual friends in common.  I don't want to create drama, but it's been over a year now and he told me he never plans on being honest with her. 

I keep thinking about what I would want if I were in her position, and I've come to the conclusion that I would want to know all of the facts.  However, I don't want to cause drama and would be perfectly happy to walk away and not bring up any old hurts.
<bot>: Had an affair last year with a married man, he hasn't told his wife and probably never will.  Should I?
