Line Them All Up And I Still Win

Dear Steve and Shirley, I've been in a relationship for twelve years and my girlfriend confessed that she cheated on me seven years ago. She blurted it out during an argument and it cut like a knife. I have never cheated on her when I could have, I remained faithful. The worst part for me is that she won't tell me who she cheated with. She thinks that clearing her conscience is enough and I should be able to deal with it and move on, but I can't. How can she halfway confess it could be one of my friends, co-workers, a guy at the gym, or even a family member?........................................................See omnystudio.com/listener for privacy information.
