I'm a guy, 35, and a cheating piece of shit. I'm engaged to a woman I love, but earlier this year I cheated on her. I have no excuse. She discovered the dating app I used, and we worked through that. But she doesn't know that shortly after her discovery, I went ahead and cheated. To my meager, meager credit, I did seek out only women who were looking for NSA hookups. But I quickly came to realize how big of a mistake this was, how much I love my fiancée, and that I'm a shitty person. I see a therapist, and he advised that, if I'm certain this was a one-time thing, and if I'm convinced that I'm happy with my fiancée, I should keep quiet. I shouldn't burden my fiancée with this knowledge. I'm inclined to agree but, dear God, the guilt. I feel like I'm not the person my fiancée thought I was. What do I do? Should I just accept this as a lesson learned and keep it to myself? Perhaps there's selfishness at play here, since I'm trying to make myself feel better, but I'm struggling.
