What if I am going to cheat?
What will happen if you cheat?
I'll lose respect from others and I'll be alone for the rest of my life, but I don't care because cheating is fun.
It is wrong to cheat on your partner.  Just don't do it.
But I've already made up my mind.
If you cheat on your partner you will never be able to take it back. Do you really want to have regrets you have to live with forever?
