I agree with what you say, but I think that most people fall heavy on only focusing on what we already all know (cheating is bad, honesty is good). There is not enough talk about true, deep, painful self reflection and asking ourselves why we hurt someone else and why (in my case) didn't feel bad about it. This has led to much more growth and becoming a better partner over the last decade than a mere acceptance that cheating is bad and I did a bad thing.
