No one wins with infidelity. As the unfaithful partner shoulders all the blame for how the relationship went south, the person cheated on may harbor resentment to a point that they may want to exact revenge.
This is what a man did when he found out his wife had betrayed him. He made it a point to make her life a living hell, all while she owned up to her mistake and did all she could to win the trust back.
Unfortunately for the woman, she is left dealing with lifelong scars, both physical and emotional, all while dealing with a massive responsibility on her own.
