I plan on cheating on my significant other.
What is your reason for wanting to cheat on your partner?
There's someone else that I really like.
If you have such a strong urge to cheat on your partner you should think about sitting down and talking to them about it. Cheating on someone will hurt them and then hurt everyone else's trust in you later down the road.
I don't care. It's my life to fuck up. I hate him.
If you feel like you hate your partner then you are better off leaving them and not being with them. Feeling the urge to cheat could be a red flag and a sign that you are better off separating.
