I cheated on my wife and don't feel bad about it.
What did she do that made you feel bad?
It had nothing to do with her, I just wanted to cheat.
It is wrong to cheat on your wife because you feel like it. It is expected couples will be honest with each other and be monogamous.
I love my wife and did it just because I wanted something different.
You should talk about that with your wife, not go cheat with another person.
