People who have cheated on their partners, why?

I know people may judge me, but the main reason was because I was young and foolish. She was always smarter than me, and I was low-key jealous of that. One day I got tempted and was weak. I thought to myself, "well maybe if she isn't looking, I'll just do something innocent like a quick glance" and that's how it started. By talking to myself and accepting it. But it was a slippery slope, and like Stanley said in The Office it really only gets easier and easier. Before I knew it, I ended up cheating on her.

The thing is that she never knew. And I started to get so good at it, I thought I would never get caught. But one day I got too cocky and let my guard down and I got caught. Let me tell you, honestly it wasn't as bad as I thought it'd be. All I got was a failed test grade, detention, and a big laugh from my lab partner.
