I think personally it's not good for anyone - I don't think infidelity leads to happiness. It's painful for the person being cheated on, but also for the person who's cheating.
I wanted to be the exception to the other kids, but in the right way. We have a lot of suffering in our part of the world, but that suffering is, in a way, a blessing. Obviously, I could not afford to go to school without a scholarship, so that meant I had to excel in order to get one.
