Don't. Don't cheat, don't advocate cheating, don't condone cheating. Just don't. But also, since this subject seems to be coming up, don't hate people for cheating, don't harm people for cheating, and don't hate or harm yourself for cheating. Cheating is going to suck for all the people involved once it comes out, bu remember who it is you care for within the relationship and try to talk it out and come to some kind of peaceful conclusion. But first of all just don't.
