I was aware that people around me thought we were a happy couple. Even when I saw a photo of him arm-in-arm with another woman going into a hotel, I couldn't believe that my husband was cheating on me. But he admitted to cheating. I never thought I would look at my husband, who had told me he would do anything to forgive me, with such cold feelings. My husband should suffer as much as I suffered. I decided to punish my husband until I felt satisfied.
