Thank you for sharing your story, Ariza. It must have been challenging on your end to recall those dark times in your life. Right when all of us want to bury everything in the past, it's brave of you to write this. And I commend you for that.
Cheating is indeed a controversial subject. And it always will be. Even I can't fathom the fascination people have when they hear stories of who cheated on who, and what who did after learning about who's affairs.
Anyway, I still think telling her was the right thing to do. Yes, it may have avoided her intense stress, anxiety, and depression, but would you really rather let her sleep peacefully yet blind to the entirety of your infidelity?
I'm not here to argue with you, but I wanted you to know that what you did was right. :) Have a great day.
