My oppinion:
I live by this: Do unto others as you would have done unto you! I try not to do things to people i wouldn't want done to me.
But.....call me a hypocrit if you like......there was this once......when i was 15......my boyfriend, who i was absolutely "in love" with, thought the world of him, (too much obviously) anyway, my friend comes home from a school retreat (my bf and friend went to same school) and tells me he cheated on me and....all the rest! Ohhhh ho ho, i was BASTARD MAD! First i cried....didn't say anything to him....i thought, cool, i can deal with it, it's cool, im a big toughy, it slowly built up and.....there was this guy who had been obsessed with me for ages...anyway one night i ring him cos i knew he's say, can i come up for a while, so...offcoarse, i said yes, knowing what would happen, i said, "hurry up before i change my mind" (what a bitch!) and he did, i cheated on my bf. Lol, i was just so angry. I liked this guy so much n felt so betrayed. So i went to my bf, made him admit what he did and he appologised...took him a whole day mind you. Never mentioned what i had gone n done. Went to school with him the year after that, he ended up finding out lol didn't really care by that stage. It made it easier to deal with, lol i just thought, payback buddy.
Before i was cheated on i always said i would never ever cheat on anyone, but i was just so angry n immature then. I won't do it again, no matter how angry i am. Lol ha ha....
