Do not tell a soul. None of your friends, family members, coworkers. And especially not her! Nobody can know.
I don’t even know how it happened. I was so drunk. Did I come onto you or did you come onto me? Either way… it was a huge mistake. And I am so sorry. I feel absolutely horrible. Your girlfriend is the sweetest, kindest girl in the world. And what we did is so wrong. I’ve never felt more ashamed in my life.
I am terrified that you might tell someone and she will find out. Or I am afraid the guilt will eat you up and you will confess to her what happened. Please. I beg of you… please don’t.
I am carrying our dirty secret to the grave.
I hope you are too.
