I was in relationship with a girl for 9.5 years but she had an affair in her college with a guy for 6 months, I was totally unaware about her affair, I came to know when she behaves violently during our communication. That guy had sexually,mentally harassed her, I know this because of spy agent I appointed. I was shocked about her act. That guy cheated her and now she want to come back to me, I am not interested what to do ?
