There's something inside of me that makes me think I'd not be able to refrain from cheating in a relationship.
What is your reason for thinking you would cheat?
I'm a cheater, I love it when I feel my actions have an impact on the relationship.
Well it is wrong to cheat while your in a relationship. Maybe getting to the bottom of why it feels good for you to cheat will help you fix the issue and have a lasting relationship.
I cheat because it's fun and I feel like I'm a smart person.
You're not a smart person when you cheat, because most people would think that you're being very bad. It's not nice to cheat and could ruin your relationships with more than just the person you're dating if others find out how you are.
